Target lemma: study
Target surface form: study
Context:
The active substance in Alimta, pemetrexed, is a cytotoxic medicine (a medicine that kills cells that are dividing, such as cancer cells), which belongs to the group antimetabolites. In the body, pemetrexed is converted into an active form that blocks the activity of the enzymes that are involved in producing nucleotides (the building blocks of DNA and RNA, the genetic material of cells). How has Alimta been studied? For the treatment of malignant pleural mesothelioma, Alimta has been studied in one main study in 456 patients who had not received chemotherapy for their disease before. The effects of Alimta in combination with cisplatin were compared with those of cisplatin alone. For the treatment of non-small cell lung cancer, the effects of Alimta were compared with those of docetaxel (another anticancer medicine) in one <t>study</t> involving 571 patients with locally advanced or metastatic disease who had received chemotherapy in the past. Alimta was also compared with gemcitabine (another anticancer medicine), both in combination with cisplatin, in a study involving 1,725 patients who had not received chemotherapy for lung cancer in the past.

reasoning_content:
The user wants me to perform Word Sense Disambiguation for the target word "study" based on the provided context.

Context analysis:
The text discusses a cytotoxic medicine (Alimta/pemetrexed) and its use in treating various cancers (malignant pleural mesothelioma, non-small cell lung cancer).
The relevant sentences are:
1. "How has Alimta been studied?" (General question about research)
2. "For the treatment of malignant pleural mesothelioma, Alimta has been studied in one main study in 456 patients..." (Specific research trial)
3. "...in one <t>study</t> involving 571 patients with locally advanced or metastatic disease..." (Referring to a clinical trial/research project)
4. "...in a study involving 1,725 patients who had not received chemotherapy for lung cancer in the past." (Referring to a clinical trial/research project)

The word "study" consistently refers to a formal piece of research, usually a clinical trial or scientific investigation, involving patients and comparing treatments.

Candidate senses analysis:
1. sense_key=study%1:04:00:: | definition=a detailed critical inspection | synonyms=survey. (Possible, but usually refers to the *act* of inspecting, not the resulting document/trial itself, though related.)
2. sense_key=study%1:09:03:: | definition=applying the mind to learning and understanding a subject (especially by reading) | synonyms=work. (Incorrect. This is about academic learning.)
3. sense_key=study%1:10:00:: | definition=a written document describing the findings of some individual or group | synonyms=report, written report. (Highly plausible. A clinical trial is a formal report/document of findings.)
4. sense_key=study%1:09:04:: | definition=a state of deep mental absorption. (Incorrect. This is about concentration.)
5. sense_key=study%1:06:00:: | definition=a room used for reading and writing and studying. (Incorrect. This is a location.)
6. sense_key=study%1:09:02:: | definition=a branch of knowledge | synonyms=discipline, subject, subject area, subject field, field, field of study. (Incorrect. This refers to a field of science, not a specific research project.)
7. sense_key=study%1:06:01:: | definition=preliminary drawing for later elaboration | synonyms=sketch. (Incorrect. This is artistic.)
8. sense_key=study%1:09:01:: | definition=attentive consideration and meditation | synonyms=cogitation. (Incorrect. This is the act of thinking deeply.)
9. sense_key=study%1:18:00:: | definition=someone who memorizes quickly and easily (as the lines for a part in a play). (Incorrect. This is a person.)
10. sense_key=study%1:10:01:: | definition=a composition intended to develop one aspect of the performer's technique. (Incorrect. This is musical.)

Revisiting the best fit:
The context refers to "Alimta has been studied in one main study in 456 patients" and "in one study involving 571 patients." These are clinical trials.
Sense 3: "a written document describing the findings of some individual or group" (synonyms: report, written report). A clinical trial is fundamentally a structured research report/document.
Sense 1: "a detailed critical inspection" (synonyms: survey). While a trial is an inspection, Sense 3 captures the formal, documented nature of the research project better, especially when referring to the final output or the structured investigation itself.

In scientific/medical contexts, "a study" almost always refers to the research project/trial, which is documented (Sense 3) or is the act of investigation (Sense 1). Given the options, Sense 3 (the formal report/document of findings) is the most precise fit for how these research projects are indexed in WordNet, especially when contrasted with the other senses.

I will choose Sense 3.

The user wants me to perform Word Sense Disambiguation for the target word "involving" (the present participle of "involve") based on the provided context.

Context: "For the treatment of non-small cell lung cancer, the effects of Alimta were compared with those of docetaxel (another anticancer medicine) in one study <t>involving</t> 571 patients with locally advanced or metastatic disease who had received chemotherapy in the past."

Target word: involving

Analysis of the context:
The phrase is "in one study involving 571 patients".
Here, "involving" describes the study. The study *has* or *contains* 571 patients as part of its scope or design.

Analysis of candidate senses:
1. sense_key=involve%2:42:01:: | definition=connect closely and often incriminatingly | synonyms=affect, regard
2. sense_key=involve%2:42:04:: | definition=engage as a participant | examples=Don't involve me in your family affairs!
3. sense_key=involve%2:42:00:: | definition=have as a necessary feature | synonyms=imply | examples=This decision involves many changes
4. sense_key=involve%2:42:07:: | definition=require as useful, just, or proper | synonyms=necessitate, ask, postulate, need, require, take | examples=It takes nerve to do what she did; success usually requires hard work
5. sense_key=involve%2:42:02:: | definition=contain as a part | examples=Dinner at Joe's always involves at least six courses

7. sense_key=involve%2:30:00:: | definition=make complex or intricate or complicated | examples=The situation was rather involved

Matching the context to the senses:
The study *contains* or *includes* 571 patients.

Sense 5: definition=contain as a part. This perfectly matches the idea that the study encompasses or contains a specific group of patients.

Let's check other close options:
Sense 2: engage as a participant. While patients are participants, "involving 571 patients" is better captured by the idea of the study *containing* them, rather than just the act of engaging them.
Sense 3: have as a necessary feature. This is close, but "contain as a part" (Sense 5) is more direct when referring to the components (patients) of a whole (study).

Sense 5 is the most precise fit.

The user wants me to perform Word Sense Disambiguation (WSD) for the target word "patients" (plural of "patient") based on the provided context.

Context analysis:
The text discusses cancer treatments (Alimta, pemetrexed, cisplatin, docetaxel, gemcitabine).
The relevant sentences are:
1. "For the treatment of malignant pleural mesothelioma, Alimta has been studied in one main study in 456 patients who had not received chemotherapy for their disease before."
2. "For the treatment of non-small cell lung cancer, the effects of Alimta were compared with those of docetaxel (another anticancer medicine) in one study involving 571 <t>patients</t> with locally advanced or metastatic disease who had received chemotherapy in the past."
3. "Alimta was also compared with gemcitabine (another anticancer medicine), both in combination with cisplatin, in a study involving 1,725 patients who had not received chemotherapy for lung cancer in the past."

In all instances, "patients" refers to individuals receiving medical treatment for cancer.

Candidate senses:
1. `sense_key=patient%1:18:00`: | definition=a person who requires medical care | examples=the number of emergency patients has grown rapidly
2. `sense_key=patient%1:10:00`: | definition=the semantic role of an entity that is not the agent but is directly involved in or affected by the happening denoted by the verb in the clause | synonyms=affected role, patient role

Evaluation:
Sense 1 clearly defines a person requiring medical care, which perfectly matches the context (people undergoing cancer treatment studies).
Sense 2 defines a grammatical/semantic role (the patient role in linguistics/semantics), which is irrelevant to the meaning of the noun "patients" in this medical context.

Conclusion: Sense 1 is the correct and best fit.

1.  **Analyze the target word and context:**
    *   Target word: "locally"
    *   Context sentence: "For the treatment of non-small cell lung cancer, the effects of Alimta were compared with those of docetaxel (another anticancer medicine) in one study involving 571 patients with <t>locally</t> advanced or metastatic disease who had received chemotherapy in the past."
    *   The context is about cancer treatment (non-small cell lung cancer) and the stage of the disease ("advanced or metastatic disease").

2.  **Analyze the candidate senses:**
    *   Sense 1: `locally%4:02:00` | definition=by a particular locality | examples=it was locally decided. (Relates to place/area, but often administrative or general location.)
    *   Sense 2: `locally%4:02:01` | definition=to a restricted area of the body | synonyms=topically | examples=apply this medicine topically. (Relates specifically to the body/medical application.)

3.  **Evaluate the fit:**
    *   The phrase is "locally advanced or metastatic disease."
    *   In oncology, "locally advanced" refers to cancer that has grown beyond the primary tumor site but has not spread to distant parts of the body (i.e., it is confined to a specific, restricted area of the body/region).
    *   Sense 2 ("to a restricted area of the body") perfectly matches the medical terminology used in the context of cancer staging (locally advanced disease).
    *   Sense 1 ("by a particular locality") is too general and does not capture the specific medical meaning related to disease progression/location within the body.

4.  **Conclusion:** Sense 2 is the best fit.

5.  **Format the output:** Return the JSON object with the correct sense index. (Sense 2 corresponds to index 2 in the provided list, assuming 1-based indexing for the final output structure, but since the prompt asks for a JSON object with a single index, I will use the index corresponding to the chosen sense.)

*Self-Correction/Refinement:* The prompt lists two candidates. I chose the second one. I must ensure the final output format is correct.

Candidate 1 -> Index 1
Candidate 2 -> Index 2

I choose Candidate 2.

Context: "For the treatment of non-small cell lung cancer, the effects of Alimta were compared with those of docetaxel (another anticancer medicine) in one study involving 571 patients with locally <t>advanced</t> or metastatic disease who had received chemotherapy in the past."

Target word: advanced
Collocation: locally advanced disease

Analysis of the context:
The context is medical/oncological. "Locally advanced disease" refers to the stage of cancer. Metastatic disease means the cancer has spread to other parts of the body. "Locally advanced" describes a stage of progression of the disease.

Evaluation of candidate senses:
1. `advanced%5:00:00:precocious:00`: Farther along in physical or mental development. (Not applicable to cancer stage.)
2. `advanced%5:00:00:late:02`: Comparatively late in a course of development. (This fits the idea of a disease reaching a later, more severe stage.)
3. `advanced%5:00:00:progressive:01`: Ahead of the times. (Relates to ideas/technology, not disease stage.)
4. `advanced%5:00:02:high:02`: At a higher level in training or knowledge or skill. (Not applicable.)
5. `advanced%5:00:00:high-tech:00`: Ahead in development; complex or intricate. (Relates to technology, not disease stage.)
6. `advanced%5:00:00:late:00`: Far along in time. (Relates to age/time, less specific than stage of disease.)
7. `advanced%5:00:00:civilized:00`: Highly developed especially in technology or industry. (Not applicable.)
8. `advanced%5:00:00:front:00`: Situated ahead or going before. (Not applicable.)

Comparing the best candidates:
Sense 2 (`advanced%5:00:00:late:02`): definition=comparatively late in a course of development; examples=the illness had reached an advanced stage; an advanced state of exhaustion.
This sense perfectly matches the medical usage of "advanced disease," meaning the disease has progressed to a late or severe stage.

Sense 6 (`advanced%5:00:00:late:00`): definition=far along in time; synonyms=ripe; examples=a man of advanced age; advanced in years.
While "late" is in the key, the definition focuses on chronological time (age), whereas the context refers to the stage of biological development/progression of the illness. Sense 2 is much more precise for the context of disease staging.

Conclusion: Sense 2 is the best fit.

The user wants me to perform Word Sense Disambiguation for the target word "compared" (lemma: compare) based on the provided context.

Context:
"The effects of Alimta in combination with cisplatin were compared with those of cisplatin alone. For the treatment of non-small cell lung cancer, the effects of Alimta were compared with those of docetaxel (another anticancer medicine) in one study involving 571 patients with locally advanced or metastatic disease who had received chemotherapy in the past. Alimta was also <t>compared</t> with gemcitabine (another anticancer medicine), both in combination with cisplatin, in a study involving 1,725 patients who had not received chemotherapy for lung cancer in the past."

The word "compared" is used in the context of clinical trials, specifically comparing the "effects" of different drugs (Alimta vs. cisplatin alone; Alimta vs. docetaxel; Alimta vs. gemcitabine).

Candidate Senses:
1. sense_key=compare%2:31:00:: | definition=examine and note the similarities or differences of | examples=John compared his haircut to his friend's; We compared notes after we had both seen the movie
2. sense_key=compare%2:42:00:: | definition=be comparable | examples=This car does not compare with our line of Mercedes
3. sense_key=compare%2:31:01:: | definition=consider or describe as similar, equal, or analogous | synonyms=liken, equate | examples=We can compare the Han dynasty to the Romans; You cannot equate success in financial matters with greed
4. sense_key=compare%2:32:00:: | definition=to form the comparative or superlative form on an adjective or adverb

Analysis:
The context requires assessing the differences or similarities in the *effects* of different medical treatments.

*   Sense 1 (examine and note the similarities or differences of): This fits perfectly. Clinical trials are designed to examine and note the differences in outcomes (effects) between treatment groups.
*   Sense 2 (be comparable): This is a state of being, not the action of comparing effects. (e.g., "The two drugs are comparable.")
*   Sense 3 (consider or describe as similar, equal, or analogous): This focuses on drawing analogies or equating concepts (e.g., comparing dynasties). While related to comparison, Sense 1 is more precise for the scientific/experimental context of testing effects.
*   Sense 4 (form the comparative or superlative form): This is grammatical usage (e.g., "fast compared to faster"). This is clearly incorrect.

Comparing Sense 1 and Sense 3:
Sense 1: "examine and note the similarities or differences of" (Focus on empirical observation/testing).
Sense 3: "consider or describe as similar, equal, or analogous" (Focus on conceptual similarity/likening).

In the context of medical research ("The effects of Alimta... were compared with those of cisplatin alone"), the researchers are actively *examining and noting the differences* in the observed effects. Sense 1 is the most accurate description of this scientific methodology.

Therefore, Sense 1 is the best fit.

Context snippet: "Alimta was also compared with gemcitabine (another anticancer <t>medicine</t>), both in combination with cisplatin, in a study involving 1,725 patients who had not received chemotherapy for lung cancer in the past."

Target word: medicine
Contextual usage: "anticancer medicine"

Candidate senses:
1. sense_key=medicine%1:09:00:: | definition=the branches of medical science that deal with nonsurgical techniques | synonyms=medical specialty (Refers to a field of study/specialty, e.g., internal medicine)
2. sense_key=medicine%1:06:00:: | definition=(medicine) something that treats or prevents or alleviates the symptoms of disease | synonyms=medication, medicament, medicinal drug (Refers to a substance/drug)

4. sense_key=medicine%1:04:02:: | definition=punishment for one's actions | synonyms=music (This seems like a mislabeled sense, but the definition is 'punishment')

Analysis:
The phrase is "anticancer medicine."
"Anticancer" means against cancer.
The word "medicine" here refers to a substance (like gemcitabine or cisplatin) used to treat cancer.

Let's evaluate the senses:
1. Medical specialty: Incorrect. It's not a field of study.
2. Something that treats or prevents or alleviates the symptoms of disease (medication/drug): Correct. An anticancer drug is a medicine in this sense.
3. Learned profession: Incorrect. It's not referring to the practice of medicine.
4. Punishment: Incorrect.

The best fit is sense 2.

reasoning_content:
1.  **Analyze the context:** The sentence is: "Alimta was also compared with gemcitabine (another anticancer medicine), both in combination with cisplatin, in a <t>study</t> involving 1,725 patients who had not received chemotherapy for lung cancer in the past."
2.  **Determine the meaning of 'study' in context:** Here, 'study' refers to a clinical trial or research investigation involving a large group of patients (1,725 patients) to compare treatments (Alimta + cisplatin vs. gemcitabine + cisplatin).
3.  **Examine the candidate senses:**
    *   1. detailed critical inspection (survey): Plausible, but often used for smaller, more qualitative reviews.
    *   2. applying the mind to learning and understanding a subject: Incorrect (learning/education).
    *   3. a written document describing the findings of some individual or group (report): This sense often encompasses the *research project* itself, especially in scientific contexts, where the project culminates in a report.
    *   4. state of deep mental absorption: Incorrect (mental state).
    *   5. room used for reading and writing and studying: Incorrect (place).
    *   6. a branch of knowledge: Incorrect (field of study).
    *   7. preliminary drawing for later elaboration: Incorrect (artistic sketch).
    *   8. attentive consideration and meditation: Incorrect (mental process).
    *   9. someone who memorizes quickly and easily: Incorrect (person).
    *   10. a composition intended to develop one aspect of the performer's technique: Incorrect (music/art).
4.  **Compare the best fits (1 and 3):**
    *   Sense 1 (detailed critical inspection/survey): While a clinical trial is a type of inspection, Sense 3 (a written document describing findings) is often used interchangeably with the *research project* itself when referring to the formal investigation (e.g., "a study involving 1,725 patients"). In scientific literature, "study" frequently refers to the entire research endeavor, which is documented in a report.
    *   Sense 3 (a written document describing the findings): This sense captures the formal, structured nature of the clinical trial described. The phrase "in a study involving 1,725 patients" refers to the entire organized research effort.

5.  **Conclusion:** Sense 3 is the most appropriate fit for a formal, large-scale clinical research investigation.

Analysis:
The phrase is "a study involving 1,725 patients". This means the study contained or comprised these patients.

Let's evaluate the senses:
1. Connect closely: Not the primary meaning here.
2. Engage as a participant: While patients are participants, the structure "study involving patients" usually means the study *included* them.
3. Have as a necessary feature: This is close, but perhaps too abstract.
4. Require: The study doesn't *require* the patients; it *has* them.
5. Contain as a part: This fits perfectly. The study contains (as a part) 1,725 patients.
6. Occupy interest: Irrelevant.
7. Make complex: Irrelevant.

Sense 5 ("contain as a part") is the most accurate fit for describing the composition of a study or group.

Therefore, sense_key=involve%2:42:02 is the best choice.

The user wants me to perform Word Sense Disambiguation (WSD) for the target word "patients" (plural of "patient") based on the provided context.

Context analysis:
The text discusses clinical trials and cancer treatments (Alimta, cisplatin, docetaxel, gemcitabine).
"For the treatment of malignant pleural mesothelioma, Alimta has been studied in one main study in 456 patients who had not received chemotherapy for their disease before."
"In all three studies, the main measure of effectiveness was how long the patients survived."

The word "patients" refers to individuals receiving medical treatment for cancer.

Candidate senses:
1. `sense_key=patient%1:18:00`: definition=a person who requires medical care | examples=the number of emergency patients has grown rapidly
2. `sense_key=patient%1:10:00`: definition=the semantic role of an entity that is not the agent but is directly involved in or affected by the happening denoted by the verb in the clause | synonyms=affected role, patient role

Evaluation:
Sense 1 clearly defines a person requiring medical care. This perfectly matches the usage in the context (people undergoing cancer treatment studies).
Sense 2 defines a grammatical/semantic role (the patient role in linguistics/semantics), which is abstract and does not fit the concrete usage of "patients" as individuals in the clinical trial.

Conclusion: Sense 1 is the correct sense.

1. sense_key=study%1:04:00:: | definition=a detailed critical inspection | synonyms=survey. (Possible, but usually refers to the *act* of inspecting, not the resulting research project.)
2. sense_key=study%1:09:03:: | definition=applying the mind to learning and understanding a subject (especially by reading) | synonyms=work. (Incorrect. This is about academic learning.)
3. sense_key=study%1:10:00:: | definition=a written document describing the findings of some individual or group | synonyms=report, written report. (This is a strong candidate. A research study results in a report.)
4. sense_key=study%1:09:04:: | definition=a state of deep mental absorption | examples=she is in a deep study. (Incorrect. This is about concentration.)
5. sense_key=study%1:06:00:: | definition=a room used for reading and writing and studying | examples=he knocked lightly on the closed door of the study. (Incorrect. This is a location.)
6. sense_key=study%1:09:02:: | definition=a branch of knowledge | synonyms=discipline, subject, subject area, subject field, field, field of study. (Incorrect. This refers to fields like 'medicine' or 'biology', not the specific research projects.)
7. sense_key=study%1:06:01:: | definition=preliminary drawing for later elaboration | synonyms=sketch. (Incorrect. This is artistic.)
8. sense_key=study%1:09:01:: | definition=attentive consideration and meditation | synonyms=cogitation. (Incorrect. This is the act of thinking.)
9. sense_key=study%1:18:00:: | definition=someone who memorizes quickly and easily (as the lines for a part in a play) | examples=he is a quick study. (Incorrect. This is a person.)
10. sense_key=study%1:10:01:: | definition=a composition intended to develop one aspect of the performer's technique | examples=a study in spiccato bowing. (Incorrect. This is musical.)

Revisiting the candidates:
The context describes clinical trials/research projects ("Alimta has been studied in one main study in 456 patients...").
Sense 3: "a written document describing the findings of some individual or group" (synonyms: report, written report). While the *study* itself is the research process, in common usage, especially in scientific contexts, "study" often refers to the entire research endeavor, which culminates in a report.

Let's check if there is a better fit. Often, the sense of "research project" or "investigation" is used. Sense 1 ("a detailed critical inspection") is close, but Sense 3 captures the output/formal nature of the research better, which is often how these terms are indexed in WordNet when referring to completed research.

However, if we interpret "study" as the *investigation* itself (the process), Sense 1 ("a detailed critical inspection") is arguably the most accurate description of a clinical trial.

Let's re-examine the relationship between Sense 1 and Sense 3.
Sense 1: Inspection/Survey (The action/process).
Sense 3: Written document/Report (The output).

The text says: "Alimta has been studied in one main study..." This refers to the *investigation*.

If I must choose the single best fit for the *research project* itself:
Sense 1 (detailed critical inspection/survey) fits the nature of a clinical trial perfectly.
Sense 3 (written document/report) fits the *result* of the trial.

Given the context of comparing effects and measuring effectiveness, the term refers to the systematic investigation. Therefore, Sense 1 is the most precise fit for the concept of a clinical trial/research project.

Let's confirm the index for Sense 1: study%1:04:00:: | definition=a detailed critical inspection | synonyms=survey.

Final decision: Sense 1.

Target word: "main"

The word "main" appears twice in the relevant part of the context:
1. "...Alimta has been studied in one **main** study..."
2. "...In all three studies, the **main** measure of effectiveness was how long the patients survived."

Let's analyze the senses:

1. **sense_key=main%5:00:00:important:00 | definition=most important element | synonyms=chief, primary, principal, master | examples=the chief aim of living; the main doors were of solid glass**
   * This sense relates to importance or being primary.
   * In "one main study," it suggests this was the primary or most significant study mentioned for that specific condition (mesothelioma).
   * In "the main measure of effectiveness," it clearly refers to the most important or primary metric used (survival time).

2. **sense_key=main%3:00:02:: | definition=(of a clause) capable of standing syntactically alone as a complete sentence | synonyms=independent | examples=the main (or independent) clause in a complex sentence has at least a subject and a verb**
   * This is a grammatical/syntactic sense (independent clause). This is clearly not applicable here.

3. **sense_key=main%5:00:00:intense:00 | definition=of force; of the greatest possible intensity | examples=by main strength**
   * This sense relates to intensity or force. This is not applicable here.

Comparing the applicable senses (1 vs 2 and 3):
Sense 1 (important/primary) fits both instances perfectly.
* "one main study" -> one primary/chief study.
* "the main measure of effectiveness" -> the primary/most important measure.

Therefore, sense 1 is the best fit.

The required output format is a JSON object with the sense index.
Sense 1 corresponds to index 1.

Analysis of the context:
"In all three studies, the main measure of effectiveness was how long the patients survived."

Here, "measure" refers to the specific metric used to judge the success (effectiveness) of the treatment. The metric is "how long the patients survived" (survival time).

Let's evaluate the candidates:
1. (Step/Maneuver): Incorrect. It's not an action taken, but a result being tracked.
2. (Quantity/Amount): Plausible, as survival time is a quantity, but this sense usually refers to the amount of a substance or general quantity.
3. (Law): Incorrect.
4. (Process of quantifying): Incorrect. The measure itself is the outcome/standard, not the act of measuring.
5. (Basis for comparison; a reference point against which other things can be evaluated): Highly relevant. Survival time is the *criterion* or *standard* used to evaluate effectiveness. Synonyms like 'standard' and 'criterion' fit perfectly.
6. (Poetry/Music): Incorrect.
7. (Music): Incorrect.
8. (Tool): Incorrect.
9. (Container): Incorrect.

Sense 5, "a basis for comparison; a reference point against which other things can be evaluated," is the most precise fit. The survival time is the standard/criterion against which the treatment's effectiveness is judged.

Therefore, sense_key=measure%1:10:03 is the correct choice.

Analysis:
The phrase is "how long the patients survived."
"Survived" refers to the duration of life after treatment/diagnosis.
The question is asking about the *duration* of survival.

Sense 1: "for an extended time or at a distant time". This matches the concept of duration (time).
Sense 2: "for an extended distance". This relates to spatial extent, which is irrelevant here.

Conclusion: Sense 1 is the correct sense.

4. sense_key=survive%2:42:03:: | definition=live longer than | synonyms=outlive, outlast | examples=She outlived her husband by many years

Analysis:
The context asks "how long the patients survived." In a medical study context, this refers to the duration of life after diagnosis or treatment, often measured as overall survival or progression-free survival.

Sense 1: "continue to live through hardship or adversity." This fits the general idea of living through a difficult period (like cancer treatment).
Sense 2: "continue in existence after (an adversity, etc.)." This is very specific to overcoming a threat (like cancer).
Sense 3: "support oneself." This relates to sustenance (e.g., living on a wage), which is irrelevant here.
Sense 4: "live longer than." This implies a comparison between two or more entities (e.g., person A lived longer than person B), which is not the primary meaning here (it's measuring the duration of life for the patients).

Comparing Sense 1 and Sense 2:
Sense 1 is broad ("continue to live through hardship or adversity").
Sense 2 is focused on "continue in existence after (an adversity, etc.)" and the example provided is "He survived the cancer against all odds."

In the context of cancer treatment studies, measuring "how long the patients survived" is fundamentally measuring their continued existence despite the disease (the adversity). Both Sense 1 and Sense 2 are plausible, but Sense 2 captures the specific nuance of enduring a severe threat (like cancer) and continuing to exist, which is the core concept of survival time in oncology.

Let's re-examine the phrasing: "how long the patients survived." This is a measure of longevity in the face of a fatal condition.

Sense 2: "continue in existence after (an adversity, etc.)." This aligns perfectly with the concept of survival time in a medical context where the adversity is the disease.

Therefore, Sense 2 is the best fit.
