Background: The role of surgery in the multidisciplinary treatment of clinical stage IIIA small cell lung cancer is yet to be verified. This study was performed to determine the benefit of surgery in patients with stage IIIA small cell lung cancer.
Methods: Patients diagnosed with stage IIIA small cell lung cancer at Shanghai Pulmonary Hospital from 2005 to 2015 were included and divided into two groups: the surgery with neoadjuvant and adjuvant chemotherapy group and the concurrent chemo-radiotherapy group. Overall survival was compared between the two groups. A multivariate Cox regression model was constructed to evaluate factors associated with overall survival.
Results: Of 69 patients with stage IIIA small cell lung cancer during the study period, 40 patients (58%) underwent surgery with neoadjuvant and adjuvant chemotherapy, and 29 patients (42%) underwent concurrent chemo-radiotherapy. Patients in the surgery with neoadjuvant and adjuvant chemotherapy group had a longer overall survival compared with patients in the concurrent chemo-radiotherapy group (median survival: 33.1 16.2 months, respectively; 2-year overall survival: 44.2% 14.9%, respectively; log-rank: P=0.045). A multivariate analysis revealed that surgery with neoadjuvant and adjuvant chemotherapy (hazard ratio: 0.374; 95% confidence interval: 0.173-0.808, P=0.012) was independently associated with overall survival.
Conclusions: Patients with stage IIIA small cell lung cancer treated with surgical resection plus chemotherapy demonstrated longer overall survival compared with those who underwent concurrent chemo-radiotherapy. Surgery may be an option for clinical stage IIIA small cell lung cancer after induction chemotherapy in selected patients.

Background: Cervical cancer is considered one of the most common gynecological malignancies with an increased incidence in developing countries. Magnetic resonance imaging (MRI) plays a valuable role in staging cervical cancer and providing valuable information necessary for selecting the appropriate treatment plan, while closely correlating with the prognosis of the patient.
Objective: The aim of this study is to assess the diagnostic value of diffusion-weighted imaging (DWI) in the preoperative loco-regional staging of cervical carcinoma.

Objective: The laparoscopic approach for locally advanced gastric cancer has recently been adopted based on the results of several randomized controlled trials (RCTs). However, findings from RCTs have not been examined at the national level. This study aimed to investigate the external validity of the Korean Laparoscopic Gastrointestinal Surgery Study-02 (KLASS-02) trial involving 13 tertiary hospitals, using data from the Korean Gastric Cancer Association (KGCA)-led nationwide survey involving 68 tertiary or general hospitals.

Background: Anti-PD-1-based immunotherapy has improved outcomes in stage IIB to IV resected melanoma patients in clinical trials. However, little is known about real-world outcomes, prognostic factors and patterns of relapse.
Methods: This is a retrospective multicenter observational study including patients with resected melanoma treated with subsequent anti-PD-1-based adjuvant immunotherapy.

: This study aims to evaluate whether the presence of isolated tumor cells (ITCs) correlates with specific stages of cutaneous melanoma, potentially shedding light on their prognostic significance and the paradoxical survival outcomes in stage IIIA. : This study analyzed cases of sentinel lymph node biopsies for cutaneous melanoma between 2021 and 2023. It included patients with CM diagnoses, available histological slides, and clinical information about the neoplasia stage.

Background: Development of secondary esophageal cancer after hematopoietic stem cell transplantation has been described; however, there is little consensus on treatment and surveillance for these patients. The objective of this study was to describe our experience treating patients with secondary esophageal cancer.
Methods: A retrospective chart review of prospectively collected data was performed to identify patients who underwent hematopoietic stem cell transplantation from 1997 to 2012 and in whom esophageal cancer developed later.
