Development and Validation of Nomogram Predicting Survival in Chinese SCLC Patients

January 8, 2023 updated by: The Second Hospital of Shandong University
In this retrospective study, patients diagnosed with SCLC between January 2011 to September 2022 were identified from database of the Second Hospital of Shandong University. Following inclusion criteria should be met: (1) Had histologically or cytologically confirmed newly diagnosed SCLC; (2) No cancer treatment has been done before; (3) Complete clinical, laboratory, imaging, treatment data and follow-up information.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The investigators classified qualitative variables according to clinical practice. Age included less than 60 years, 61-66 years, and more than 67 years. The primary tumor location included left-sided and right-sided. The anatomic sites included lower and others. The smoking status included never smoker and ever smoker. The forms of performance status according to the Eastern Cooperative Oncology Group scale (ECOG PS) were ECOG ≤ 2, and ECOG ≥ 3. Five groups were formed according to clinical T stage (T0-1, T2, T3, T4, and T stage that could not be evaluated). Three groups were formed according to clinical N stage (N0-1, N2-3, and N stage that could not be evaluated). Some stages were unevaluated, on account of a portion of non-measurable tumor size and lymph node. Three groups were formed according to clinical M stage (M0, Ma-b, Mc). Four groups were formed according to clinical TNM stage (Ⅰ-Ⅱ, Ⅲ, Ⅳ and TNM stage that could not be evaluated). The common metastatic sites(brain, liver, and bone) of tumor was divided into none and yes. The hematologic markers (serum natrium , lactate dehydrogenase, carcinoembryonic antigen, neuron-specific enolase, cytokeratin 19 fragment, and pro-gastrin-releasing peptide) were divided into normal and abnormal. The above information was collected before treatment. The RECIST version 1.0 was used to assess tumor responses after initial imaging studies of commencing chemotherapy. Initial chemotherapy response is the first imaging examination of SCLC patient after starting chemotherapy. Six groups were formed according to initial response to chemotherapy (CR, PR, SD, PD, response that could not be evaluated, and no chemotherapy). Other treatments (radiotherapy, surgery, targeted therapy, immunotherapy, Interventional therapy, and whole-brain prophylactic cranial irradiation) was classified none and yes.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Observational

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
training cohort

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
