Objectives: To investigate the incidence, laryngeal distribution, management, and postoperative clinical course of patients with newly diagnosed adult-onset recurrent respiratory papillomatosis (RRP) in Japan.
Methods: An initial brief questionnaire was sent to 782 institutions, including all 101 core and 627 collaborating institutions providing board certification programs accredited by the Japanese Society of Otorhinolaryngology-Head and Neck Surgery. A detailed questionnaire regarding patient age, sex, Derkay's score, surgery, and postoperative clinical course was sent to 196 institutions caring for patients with either newly or previously diagnosed RRP.
Article Synopsis
- - The study investigates how splenic vein occlusion (SpVO) from pancreatic tumors affects surgical outcomes and complications in patients undergoing distal pancreatectomy (DP).
- - Out of 124 patients analyzed, 20.8% had SpVO, leading to longer surgery times and more postoperative complications compared to those with open splenic veins.
- - The findings suggest that understanding collateral circulation patterns can aid in better surgical planning to minimize complications related to left-sided portal hypertension caused by SpVO.
Article Synopsis
- Cricothyrotomy is a procedure used to secure an airway in emergency situations and can also help patients expel sputum; however, its overall safety and effectiveness are still being evaluated.
- A nationwide survey in Japan involved data from 1,001 patients across 116 healthcare facilities between 2010 and 2021, highlighting that most cricothyrotomies (94.4%) were performed for sputum suctioning post-surgery, primarily after esophagectomy.
- Results indicated lower complication rates for sputum suctioning compared to emergency airway clearance, suggesting that cricothyrotomy is safer for patients recovering from esophagectomy, but additional research is necessary to confirm its benefits.
Background: Second primary esophageal cancer often develops in patients with head and neck cancer, and esophagectomy in patients with a history of total pharyngolaryngectomy (TPL) is challenging. However, the clinical outcomes of these patients have yet to be examined in a multicenter setting.
Methods: We evaluated the surgical outcomes of a nationwide cohort of 62 patients who underwent esophagectomy for esophageal cancer with a history of TPL.
Objectives: This study explored the information needs and requirements of patients with pancreatic cancer (PPCs) and their families through patients' and families' views and preferences (PVPs) collected by healthcare professionals (HCPs) and to identify differences in PVPs by profession.
Methods: We conducted an anonymous web-based survey of HCPs in cancer care hospitals in Japan, posing specific questions from patients or families regarding pancreatic cancer within the past year. We qualitatively analysed the data and classified them into several categories according to their content.
Background And Objectives: This study aimed to assess the effectiveness of Comprehensive Geriatric Assessment (CGA) in customizing care for elderly cancer patients, specifically focusing on colorectal cancer. The research compared treatment strategies and outcomes in older adults considered for surgery before and after the initiation of a Geriatric Oncology Service (GOS).
Methods: Conducting a comparative study, two cohorts of consecutive colorectal cancer patients aged 75 or older were examined: the control group (n = 156) and the GOS group (n = 158).

View Article and Find Full Text PDFBackground/aim: Recent research has demonstrated that laparoscopic multivisceral resection (MVR) for advanced colorectal cancer is safe, practicable, and yields satisfactory oncological results, which is in line with the growing usage of laparoscopic surgery. The effectiveness of laparoscopic MVR is still debatable, though. The goal of this study was to compare the short- and long-term results of patients with advanced colorectal cancer treated with open MVR with laparoscopic procedures.

Purpose: The relationship between board certification, clinical guideline implementation, and quality of gastric cancer surgery remains unclear.
Methods: A web-based questionnaire survey was administered to departments registered in the National Clinical Database (NCD) of Japan between October 2014 and January 2015. Quality indicators (QIs) based on the Donabedian model were evaluated.
Aim: This study was performed to investigate the relationship between the preoperative cachexia index (CXI) and long-term outcomes in patients who have undergone radical resection of pancreatic ductal adenocarcinoma (PDAC).
Methods: In total, 144 patients who underwent pancreatic resection for treatment of PDAC were retrospectively analyzed. The relationship between the CXI and the patients' long-term outcomes after PDAC resection was investigated.
Background: Liver metastasis of pure squamous cell carcinoma (SCC) from pancreatic ductal adenocarcinoma has not been previously reported.
Case Presentation: A 66-year-old man underwent a computed tomography scan 3 years after surgery for pancreatic head cancer, and the scan revealed a mass lesion in the right lobe of the liver. A liver tumor biopsy was performed, and SCC was diagnosed.
Chronic expanding hematoma (CEH) is defined as a hematoma that grows slowly over a month or longer. CEH with a primary hepatic origin is extremely rare. An 85-year-old man presented with general malaise and low-grade fever.

Article Synopsis
- Pancreatic ductal adenocarcinoma (PDAC) frequently reoccurs quickly after surgery, indicating a poorer prognosis, making the prediction of early recurrence (ER) crucial for optimal treatment.
- A study of 153 patients analyzed various clinical factors to distinguish between those who experienced ER and those who didn't, identifying key predictors such as platelet count, CA19-9 levels, tumor size, and lymph node metastasis.
- A new prediction model based on these factors demonstrated promising accuracy, with an area under the curve of 0.763, sensitivity of 85.2%, and specificity of 55.6%, allowing for better prognosis and treatment planning for PDAC patients.
Background/aim: This study aimed to evaluate the clinical impact of the level of inferior mesenteric artery (IMA) ligation in patients with advanced low rectal cancer.
Patients And Methods: All enrolled patients (n=350) underwent curative resection of rectal cancer with D3 lymph node dissection, with either IMA (high-tie) or superior rectal artery (SRA) (low-tie) ligation.
Results: There were 27 and 65 patients in the high-tie and low-tie groups, respectively.
This systematic review was performed to investigate the superiority of proton beam therapy (PBT) to photon-based radiotherapy (RT) in treating esophageal cancer patients, especially those with poor cardiopulmonary function. The MEDLINE (PubMed) and ICHUSHI (Japana Centra Revuo Medicina) databases were searched from January 2000 to August 2020 for studies evaluating one end point at least as follows; overall survival, progression-free survival, grade ≥ 3 cardiopulmonary toxicities, dose-volume histograms, or lymphopenia or absolute lymphocyte counts (ALCs) in esophageal cancer patients treated with PBT or photon-based RT. Of 286 selected studies, 23 including 1 randomized control study, 2 propensity matched analyses, and 20 cohort studies were eligible for qualitative review.

We compared survival outcomes on older adults with advanced cancer before and after the initiation of a geriatric oncology service (GOS) in a single Japanese cancer center.
Methods: This was a comparative study of two groups of consecutive patients 70 years and older with advanced cancer who were referred to medical oncology for first-line chemotherapy before (controls; n = 151, September 2015-August 2018) and after (GOS; n = 191, September 2018-March 2021) implementation of the GOS.

Objectives: Thoracotomy is a reliable approach for descending necrotizing mediastinitis (DNM), and the use of video-assisted thoracic surgery (VATS), a minimally invasive procedure, has been increasing. However, which approach is more effective for DNM treatment is controversial.
Methods: We analysed patients who underwent mediastinal drainage via VATS or thoracotomy, using a database with DNM from 2012 to 2016 in Japan, which was constructed by the Japanese Association for Chest Surgery and the Japan Broncho-esophagological Society.
Background: The clinical features of postoperative primary tracheobronchial necrosis (P-TBN; the necrosis without anastomotic leakage or other cervical and mediastinal abscess) remains unclear. This nationwide multicenter retrospective study first investigated the clinical features of P-TBN after esophagectomy for upper aerodigestive tract cancer with a large cohort.
Methods: As a study of the Japan Broncho-Esophagological Society, a nationwide questionnaire survey was conducted in 67 institutions.
