Abstract Pulmonary sclerosing pneumocytoma (PSP) is pathologically classified as an adenoma and behaves in a benign manner. However, some cases of PSP displayed pathologically malignant behavior, such as lymph node metastasis and necrosis. A 64-year-old woman was referred to our hospital complaining of a cough and breathlessness. Histopathological analysis of the resected specimen by left pneumonectomy and lymph node dissection revealed a large PSP measuring 15 × 14 cm in size, with massive necrosis and vascular invasion. This case was the largest ever reported and suggested that clinico-histological presentation of PSP sometimes showed an aggressive phenotype like advanced lung cancer.

Early Adenocarcinoma

Abstract   Incidence of adenocarcinoma of the esophagogastric junction is increasing in Japan. However, in early cases (T1), there is no consensus on treatment strategy. The purpose of this study was to determine the optimal range of resection and lymph node dissection according to lymph node metastasis status and vascular invasion in early adenocarcinoma (T1) of the esophagogastric junction. Methods We investigated patient characteristics, surgical procedures, recurrence pattern, and optimum extent of lymph node dissection in 22 patients who underwent surgery in our hospital from 2000 to 2016 and were diagnosed with early adenocarcinoma of the esophagogastric junction (by Nishi’s classification). Results Four patients with lymph node metastasis, the depth of invasion was sm2 and lymphatic invasion was positive (ly1–ly3, focal lymphatic invasion to prominent lymphatic invasion). In all cases, the site of lymph node metastasis was the lesser gastric curvature. None of the patients developed postoperative lymph node recurrence. An examination of the outcomes revealed that the metastases were hematogenous in all patients with a depth of invasion of sm2 and a positive venous invasion (v1, focal vascular invasion). Conclusion We conclude that transhiatal esophagectomy should be selected as a minimal requirement, and that dissection of the abdominal lymph node (particularly on the lesser curvature side of the superior part of the stomach) is sufficient, for patients with early adenocarcinoma of the esophagogastric junction. In cases where the depth of invasion is sm2 or greater and vascular invasion is present, patients may require adjuvant therapy regardless of lymph node metastasis status.

Background and AimsThe current guidelines for the treatment of penile cancer patients with clinically non-invasive normal inguinal lymph nodes are still broad, so the purpose of this study is to determine which patients are suitable for lymph node dissection (LND).MethodsHistologically confirmed penile cancer patients (primary site labeled as C60.9-Penis) from 2004 to 2016 in the Surveillance, Epidemiology, and Results database were included in this analysis. Univariate and multivariate Cox regression analyses were applied to determine an overall estimate of LND on overall survival and cancer-specific survival. A 1:1 propensity matching analysis (PSM) was applied to enroll balanced baseline cohort, and further Kaplan–Meier (KM) survival analysis was used to get more reliable results.ResultsOut of 4,458 histologically confirmed penile cancer patients with complete follow-up information, 1,052 patients were finally enrolled in this analysis. Age, pathological grade, T stage, and LND were identified as significant predictors for overall survival (OS) in the univariate Cox analysis. In the multivariate Cox regression, age, pathological grade, T stage, and LND were found significant. The same results were also found in the univariate and multivariate Cox regression analyses for cancer-specific survival (CSS). After the successful PSM, further KM analysis revealed that LND could bring significant OS and CSS benefits for T3T4 patients without lymph node metastasis.ConclusionLymph node dissection may bring survival benefits for penile cancer patients without preoperatively detectable lymph node metastasis, especially for T3T4 stage patients. Further randomized control trial is needed.

Objective: The aim of this study was to identify predictive factors for pathologic central lymph node metastasis (CLNM) in patients with clinically negative CLNM (cN0) papillary thyroid microcarcinoma (PTMC) to suggest a specific group of cN0 PTMC patients who has benefit from prophylactic central lymph node dissection (CLND). Background: PTMC have excellent prognosis, however, 8% have recurrent disease. Recurrence is associated with regional lymph node metastasis. It has been reported that pathologic CLNM is found in 30 to 65% of cN0 PTMC patients. However, prophylactic CLND for cN0 PTMC remains controversial. Methods: We reviewed the records of papillary thyroid carcinoma patients with a tumor size on preoperative ultrasonography (US) of ≤ 10 mm and negative CLNM on preoperative physical examination, US, and positron emission tomography/computed tomography (PET/CT), who underwent total thyroidectomy or thyroid lobectomy with prophylactic CLND between April 2010 and February 2013. In total, 163 patients were included. We evaluated the relationship between preoperatively assessable factors including age, gender, body mass index, preoperative metformin use, primary tumor size through preoperative US, the maximum standardized uptake value (SUVmax) of the primary tumor through preoperative PET/CT, and the bilaterality of the primary tumor and pathologic CLNM. Results: A SUVmax of the primary tumor of > 3 was an independent preoperatively assessable factor predictive of pathologic CLNM in cN0 PTMC patients. Conclusions: Prophylactic CLND might be considered in cN0 PTMC patients with a SUVmax of the primary tumor of > 3 to reduce the risks of residual CLNM and recurrence.
