AI Article Synopsis

  • This study focuses on very elderly patients (80 years and older) with small-cell lung cancer (SCLC), highlighting a lack of published data on their outcomes.
  • Out of 146 patients, survival rates varied significantly based on treatment options, with those receiving aggressive therapies (chemotherapy plus local therapy) achieving the longest median survival of 14.4 months, compared to just 1.3 months for those not receiving any treatment.
  • The findings suggest that while older patients may have limited health reserves, they can benefit from intensive treatment, and recommend the need for geriatric assessments and tailored support for these individuals.

Article Abstract

Background: This analysis was performed to describe the outcome of very elderly (≥ 80 years) patients with small-cell lung cancer (SCLC) as there is no published data regarding these patients.

Materials And Methods: One hundred forty-six very elderly patients with SCLC were identified from the Institutional Lung Cancer Database ranging in age from 80 to 92 years (median, 82 years). Of these, 47 (32%) patients had limited-stage SCLC (L-SCLC), and 99 (68%) had extensive-stage SCLC (E-SCLC). All were Caucasian, and the majority (64%) were female. Sixty-seven (46%) patients had Zubrod performance status (PS) of 0 to 1.

Results: Of the 146 patients, 44 (30%) received no therapy, 65 (45%) received chemotherapy alone, 27 (19%) received chemotherapy plus local therapy (thoracic radiotherapy [TRT] or surgery), and 10 (7%) received local therapy alone. The median survival was 5.4 months. On univariable analysis, age (P = .019), stage (L-SCLC vs. E-SCLC; P = .0002), PS (P < .0001), and treatment option (P < .0001) were associated with survival. On multivariable analysis, stage (P = .011), PS (P = .029), and treatment option (P < .0001) maintained significance. For entire cohort, the median survival was 1.3 months without active therapy, 6 months with local therapy alone, 7.2 months with chemotherapy alone, and 14.4 months with chemotherapy plus local therapy (P < .0001, univariable and multivariable). Similar survival findings in response to treatment were found when the L-SCLC and E-SCLC cohorts were separately analyzed.

Conclusions: The survival of very elderly patients with SCLC was associated with stage (L-SCLC vs. E-SCLC), PS, and treatment option. Very elderly patients with SCLC often have limited functional reserve required to tolerate aggressive multimodality therapy but appeared to benefit from it. Geriatric assessments, careful monitoring, and extra support are warranted in elderly patients. Care should be individualized based on the desires and needs of each patient.

Aim: Breast cancer is the most common cancer in women and is a leading cause of cancer-related mortality. The role of neoadjuvant therapy (NAT) in conjunction with surgical intervention is becoming increasingly prominent in the field of oncology. NAT enhance the probability of breast-conserving surgery in cases of locally advanced breast cancer and in patients with metastatic or inoperable disease.

Aim: Colorectal cancer (CRC) ranks as the second most diagnosed and third most deadly cancer worldwide. Despite advances in early diagnosis and treatment, CRC remains a leading cause of cancer-related deaths. Up to 30% of CRC patients are diagnosed during emergency department visits, leading to surgical procedures that may not adhere to oncological principles due to complications like obstruction, bleeding, or perforation.

Unveiling the Masquerade: Early Gastric Cancer Mimicking Advanced Disease with Ectopic Pancreas Intrusion.

Gastric cancer is a significant health concern worldwide, and its diagnosis and management are of paramount importance. Ectopic pancreas (EP) refers to an embryological abnormality where healthy pancreatic tissue develops without anatomical, vascular, or neural communication with the normal pancreas. We report the case of a patient whose initial endoscopic evaluation suggested early gastric cancer, but computed tomography scan (CT scan) and endoscopic ultrasound (EUS) indicated a locally advanced tumor.

Neurosurgery Unit, Department of Head and Neck Surgery, Garibaldi Hospital, 95124 Catania, Italy.

Aim: This systematic review aims to synthesize the epidemiology, clinical presentation, diagnostic approaches, treatment strategies, and outcomes of spinal dumbbell meningiomas to enhance understanding and improve patient management.

Methods: Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, four major databases (PubMed, Scopus, Web of Science, and Cochrane Library) were searched until June 2024. Studies included patients diagnosed with spinal dumbbell intradural-extradural meningiomas, focusing on patient demographics, tumor characteristics, diagnostic methods, treatment modalities, and clinical outcomes.

Objective: To evaluate whether supracricoid partial laryngectomy (SCPL) may be a viable alternative to radiation therapy (RT) for patients with glottic cT3N0M0 squamous cell carcinoma (SCC) who are surgical candidates for total laryngectomy (TL) and respond well to platinum-based induction chemotherapy.

Methods: Retrospective case series review of 18 consecutive patients with cT3N0M0 glottic SCC, initially considered surgical candidates only for TL who showed a good response to platinum-based induction chemotherapy, managed at a French university teaching institution with either SCPL (n = 9) or RT (n = 9). The main endpoints were 10-year local control and laryngeal preservation.
