Trastuzumab deruxtecan (T-DXd) frequently induces interstitial lung disease (ILD) more than other anti-human epidermal growth factor receptor 2 therapies. We diagnosed two cases of ILD induced by T-DXd in patients with advanced breast cancer. The first case is that of a 57-year-old Japanese woman who complained of dyspnoea and fever after 4 cycles of T-DXd.

Objective: We examined the applicability and safety of staging laparoscopy(SL)in the treatment of advanced gastric cancer.

Methods: We retrospectively reviewed the gastric cancer cases that were examined using SL between January 2015 and December 2019 at our hospital.

Results: Within this period, 59 gastric cancer patients underwent SL, of whom 53 were diagnosed with SL at first examination.

The patient was an 81-year-old man. Laparoscopic sigmoidectomy was performed for a sigmoid colon cancer(S, type 2, pT3[SS], INF a, Ly0, V0, BD1, Pn0, pPM0, pDM0, RM0, pN0, pM0, pStage Ⅲa, R0, Cur A). One year after the surgery, a blood test showed CEA as high as 68.

Background: Frailty results in a high risk for disability, hospitalization, and mortality. This study aimed to investigate perioperative details of frail patients who underwent pancreatectomy and whether frailty can be a predictive factor of postoperative complications, especially of clinically relevant postoperative pancreatic fistula (CR-POPF).

Methods: This retrospective study included patients who underwent pancreatectomy in our hospital between August 2016 and March 2019.

Background: Although the effectiveness of epidural anesthesia on pain control after esophagectomy has been reported, the appropriate insertion level of the epidural catheter remains unclear for adequate postoperative pain control. We investigated the relationship between the epidural catheter insertion level and postoperative pain control after esophagectomy for esophageal cancer.

Methods: We analyzed retrospectively 63 patients who underwent McKeown esophagectomy for esophageal cancer between October 2014 and November 2018.

The patient was a 62-year-old man with no specific medical history. Lateral segmentectomy was performed for hepatocellular carcinoma with a tumor size of approximately 14×13 cm. The histopathological diagnosis was moderately differentiated hepatocellular carcinoma: Fc(-), Fc-Inf(-), Sf(-), S0, N0, Vp2, Vv1, Va0, B0, P0, SM(-), CH.

Background: Benign esophageal tumors are relatively rare, and a neurofibroma in the esophagus is extremely rare. Dysphagia is the most common clinical manifestation in patients with esophageal neurofibroma, and no cases of giant esophageal neurofibroma with severe tracheal stenosis have been reported.

Case Presentation: A 73-year-old woman presented with shortness of breath, and computed tomography scan exhibited a giant mediastinal tumor causing severe tracheal stenosis.

Introduction: The incidence of remnant gastric cancer is increasing because of past use of subtotal gastrectomy to treat peptic ulcer and increased survival rates after radical gastrectomy for gastric cancer. The feasibility and advantages of laparoscopic total gastrectomy (LTG) for remnant gastric cancer remain unclear. Therefore, we aimed to investigate the safety, feasibility, and clinical short-term outcomes of LTG for remnant gastric cancer.

Unresectable locally advanced breast cancer results in a decline in patient quality of life because of the presence of bleeding, exudates, and strong odor. The clinical application of supportive care using Mohs paste for improving quality of life has become widespread. We report 2 cases of locally advanced breast cancer treated with systemic therapy and chemosurgery.

For treatment of colorectal liver metastases, liver resection is recommended for resectable cases in the clinical guidelines for colorectal cancer. On the other hand, there are currently no data supporting the efficacy of radiation therapy as a topical treatment, and this treatment can therefore not presently be recommended. With CyberKnife®, it is possible to perform stereotactic radiation therapy using a linear accelerator with high accuracy, even for lesions in the trunk area such as liver metastases.

We report on a patient who underwent total gastrectomy with D2 lymph node dissection for metastatic gastric cancer. We administered S-1 at 60 mg/m² as postoperative adjuvant chemotherapy. Six months after surgery, recurrence was detected in the para-aortic lymph node.

The efficacy and safety of nanoparticle albumin-bound paclitaxel(nab-paclitaxel)administered every 3 weeks for unresectable or recurrent gastric cancer was evaluated retrospectively. Nab-paclitaxel was intravenously administered at 260 mg/ m² on day 1 of each 21-day course without anti-allergic premedication until disease progression or discontinuation. Nine patients received nab-paclitaxel.

The patient was a 51-year-old woman who presented with nausea, vomiting, and abdominal pain. Detailed examination revealed a carcinoma of the descending colon with simultaneous hepatic metastasis. Because the carcinoma comprised a circumferential stenotic lesion and resection of the hepatic metastasis was feasible, combined left hemicolectomy and hepatectomy were initially performed.

A 70-year-old woman was diagnosed as having advanced lower thoracic esophageal cancer with abdominal lymph node metastases(T3N1M0, Stage III). After administering 2 courses of neoadjuvant chemotherapy with 5-fluorouracil(5- FU)( 800 mg/m2)and cisplatin(80 mg/m2), we performed curative surgery with D2 lymph node dissection. The patient could not receive adjuvant chemotherapy because of her poor performance status.

Bouveret's syndrome, which is a gastric outlet obstruction caused by a gallstone in the duodenum, is a rare complication of gallstone disease. We report a case of Bouveret's syndrome in an 81-year-old woman who also exhibited incidental gallbladder cancer. She was admitted to our hospital complaining of upper abdominal pain and vomiting.
