ABSTRACT
BACKGROUND AND OBJECTIVES: Adenocarcinoma patterns could be grouped based on clinical behaviors: low- (lepidic), intermediate- (papillary or acinar), and high-grade (micropapillary and solid). We analyzed the impact of the second predominant pattern (SPP) on disease-free survival (DFS). METHODS: We retrospectively collected data of surgically resected stage I and II adenocarcinoma. SELECTION CRITERIA: anatomical resection with lymphadenectomy and pathological N0. Pure adenocarcinomas and mucinous subtypes were excluded. Recurrence rate and factors affecting DFS were analyzed according to the SPP focusing on intermediate-grade predominant pattern adenocarcinomas. RESULTS: Among 270 patients, 55% were male. The mean age was 68.3 years. SPP pattern appeared as follows: lepidic 43.0%, papillary 23.0%, solid 14.4%, acinar 11.9%, and micropapillary 7.8%. The recurrence rate was 21.5% and 5-year DFS was 71.1%. No difference in DFS was found according to SPP (p = .522). In patients with high-grade SPP, the percentage of SPP, age, and tumor size significantly influenced DFS (p = .016). In patients with lepidic SPP, size, male gender, and lymph-node sampling (p = .005; p = .014; p = .038, respectively) significantly influenced DFS. CONCLUSIONS: The impact of SPP on DFS is not homogeneous in a subset of patients with the intermediate-grade predominant patterns. The influence of high-grade SPP on DFS is related to its proportion in the tumor.

Classic Hodgkin lymphomas are neoplasms originating from lymphoid tissue. Primary extra-nodal classic Hodgkin lymphoma (PE-cHL) of the lung is rare. A 37-years-old Caucasian male was referred to our hospital for recurrent episodes of hemoptysis, cough and bronchitis. A computed tomography (CT) scan showed a massive left upper lung consolidation, which was positive at the positron emission tomography (PET) scan. After several inconclusive tests and no benefit from medical therapies, the patient underwent a left upper lobectomy; pathology report showed a classical type Hodgkin lymphoma with no lymph-nodes involvement. Four cycles of adjuvant chemotherapy were administered with no toxicity. At the last follow up 14 months after surgery, the patient is alive and free from disease. Primary extra-nodal classical Hodgkin lymphoma of the lung is a rare entity, but it should be considered as a differential diagnosis in young patients with pulmonary consolidation even without systemic symptoms.

BACKGROUND: Diaphragmatic endometriosis is a rare presentation of endometriosis and no standardized technique for surgical treatment is available so far. We aim to verify and describe feasibility, safety and post-operative outcomes of patients affected by diaphragmatic endometriosis treated with a minimally invasive video-assisted thoracic approach. METHODS: We prospectively collected data of all patients we operated on at our Institution for diaphragmatic endometriosis between 2015 and 2019. We included all patients with a previous histological diagnosis of pelvic or abdominal endometriosis who have complained chronic thoracic pain or who had two or more episodes of pneumothorax with or without radiological evidence of pleural and diaphragmatic endometriosis. RESULTS: During the study period, we operated on 22 patients, 20 on the right side, one on the left side and one bilaterally. Indication for surgery was based on symptoms and/or radiological evidence of diaphragmatic disease. Diaphragm was resected and reconstructed according to intraoperative findings; in 11 cases, an additional mesh was used to reinforce the suture. According to our experience with VATS, we shift from an open approach to a uniportal VATS technique. CONCLUSIONS: Surgery for diaphragmatic endometriosis can be safely performed using a minimally invasive VATS approach, which is feasible and safe even when more extensive diaphragmatic resections are required, and it allows a lower post-operative pain compared to the open approach. Moreover, uniportal VATS approach guarantees similar outcomes with better cosmetic results.
