Background Inclusion of surgery in the treatment of T4 lung cancer has been a debate for the last two decades. The aim of this study is to investigate the potential prognostic factors which could affect the outcome. Methods Fifty-seven clinical T4 non-small cell lung carcinoma (NSCLC) patients out of 716 lung resections, who were operated at a single institution in 7 years period, were included in this study. Patients are grouped into three groups as patients with neoadjuvant treatment group (group 1 n: 16), salvage surgery group (surgery after 3 months of definitive chemotherapy and radiotherapy) (group 2 n: 14), and straightforward surgery group (group 3 n: 27) with adjuvant treatment. Groups were analyzed and compared in terms of postoperative complications, 30 days of mortality, disease free survival, and overall survival. Results Mean overall survival (OS) was 48.43 ± 4.4 months and mean disease-free survival (DFS) 40.55 ± 4.46 months for all patients. Thirty days mortality was 5.2% and complication rates were 63.1%. Two years OS was 61.4 ± 6.4%, DFS was 58.1 ± 7.8%. Group 1, Group 2, and Group 3 patients had mean 39.14 ± 5.6, 44.7 ± 7.1, and 62.9 ± 4.8 months for OS (p: 0.09), and 29.6 ± 7.2, 38.4 ± 9.1, and 46.9 ± 6 months for DFS (p: 0.27). Patients who received blood transfusion showed significantly worse outcomes (p: 0.001 for DFS and p: 0.004 for OS). Conclusion According to our outcomes, surgery should be included in the treatment of clinical T4 lung cancer when physiologically and oncologically possible with careful patient selection. This study demonstrates that patients receiving straightforward surgery have longer survival, in spite of higher perioperative mortality rate. Risks and benefits should be considered carefully.

Background Acral lentiginous and mucosal melanoma that represent lesions without cumulative sun-induced damages account for 65% of melanomas among Asians but constitute only 5% in Caucasians. The distinct clinical manifestations might influence the clinical course, response to treatment, and outcomes. Factors associated with the prognosis of high-risk resected melanoma in Asians are still rarely reported. Methods Clinical, histological determinants of non-distant metastatic melanoma patients who underwent complete resection in 2014–9 were analyzed. Results Mucosal melanoma, nodular melanoma, and acral lentiginous melanoma accounted for 45.1%, 40.2%, and 14.2% of total melanoma cases (N = 82), respectively. Among cutaneous melanomas, all patients were diagnosed with Breslow's depth more than 4 mm (T4), 51% with ulceration, 95.6% with diameter more than 6 mm, 59% with lympho-vascular invasion, and 74% with regional lymph node infiltration. In mucosal melanomas, 78.3% were diagnosed in advanced stages, 14.5% with regional spread to lymph nodes and 77% with regional infiltration beyond mucosa. Lesions with ulceration were associated with higher risk of distant metastasis (OR 3.003, 95%CI:1.01–9.09). Infiltration into regional lymph node was associated with shorter overall survival (median survivals were 17 vs 23.4 months, Mantel-Cox test P = 0.049). Patients diagnosed at Breslow T4 were also associated with poorer overall survival than T1-3 (median survivals were 23 vs 32 months, Mantel-Cox test P = 0.047). Conclusion The majority of melanoma patients in our population were diagnosed in advanced stages with a higher risk for recurrence and progression into distant metastasis. Regional lymph node involvement and thicker tumor (T4) were associated with poor prognosis., Highlights • Most of melanoma patients in Indonesia are diagnosed with high-risk of progression and worse survival. • Revealing factors-associated with high-risk of disease progression is important to set up surveillance program. • Refinement of public education and care delivery are required to advance management of melanoma in Indonesia.

This paper reports on the characteristics, treatment modalities, and outcomes of patients with superior sulcus tumors who underwent surgery over a period of 15 years in 1 institution. Clinical records of 94 consecutive patients operated on by the same surgical team for non–small cell lung cancer between July 1998 and December 2013 were retrospectively reviewed. All patients received lung and chest wall en bloc resection. Forty-eight (51%) received induction treatments. Surgery was an anterior approach in 46 patients (48.9%), Paulson incision in 35 (37.2%), and a combined approach in 13 (13.8%). Lung resections were 78 lobectomies (83%), 3 were pneumonectomies (3.2%), 6 were bronchoplastic reconstructions (6.4%), and 7 were wedge resections (7.4%). Nodal dissection was systematic in 96% of patients. The median number of resected ribs was 2 (1-5), chest wall residual defect was reconstructed in 42 patients (44.7%), and 21 patients had an associated vascular resection (22.3%). Resection was radical in 85 patients (90.4%). Overall 90-day mortality was 9.6%. After a median follow-up of 1.9 years, 5-year and 10-year overall survival rates were 35% and 23%, respectively. A lower 5-year survival was observed in patients with nodal disease (48% in N0 vs 18% in N+; P < 0.0001), incomplete resection (21% for incomplete vs 37% for complete resection; P = 0.15), and anteriorly located tumor (anterior vs posterior: 26% vs 50%; P = 0.05). Pancoast tumor is a severe condition, but long-term survival may be achieved in selected cases. Nodal involvement, completeness of resection, and vascular invasion are the most important prognostic factors, and induction treatment may play a role.
