[Laparoscopic Surgery for Gastric Gastrointestinal Stromal Tumors].

Gastric gastrointestinal stromal tumors(GISTs)are rarely accompanied by lymph node metastasis; therefore, laparoscopic partial gastrectomy is feasible for managing GISTs. Between 2005 and 2022, 60 patients underwent open or laparoscopic surgery for preoperatively suspected or histopathologically confirmed GISTs. Tumors were detected in the upper, mid, and lower stomach in 38, 18, and 4 patients, respectively.

[Local Recurrence of Rectal Cancer under Perineal Skin after Abdominoperineal Resection].

A woman in her early 50s underwent abdominoperineal resection with left lateral lymph node resection for advanced rectal cancer. The pathological diagnosis was RC, RbP, well-differentiated, type 5, 65×47mm, pT3(A), pN0(0/40), M0, pStage Ⅱ. The local recurrence discovered under the perineal skin 2 months later was treated by resecting the tumor and both inguinal lymph nodes.

[Case Report of Long-Term Survival for Stage IV Advanced Sigmoid Colon Cancer with Para-Aortic Nodes by R0 Resection and Chemotherapy].

The patient was a man in his early 30s. He underwent sigmoidectomy with D3+ #216 for advanced sigmoid colon cancer with metastatic para-aortic lymph nodes. The pathological diagnosis was colon cancer(S), type 2, moderately differentiated, pT4a(SE), pN3(19/33), pM1a(LYM), pStage IV , KRAS wild-type, EGFR(+).

[Assessment of Short-Term Outcomes of Laparoscopic-Assisted Distal Gastrectomy in Elderly Patients Using Comorbidities as Predictive Factors].

Laparoscopic-assisted distal gastrectomy(LADG)is a recently developed minimally invasive surgery for management of early gastric cancer. We describe short-term results obtained from a retrospective study of LADG, performed in elderly patients, using comorbidities as predictive factors. We studied 160 patients diagnosed with gastric cancer who underwent LADG between January 2005 and October 2016.

[Radiofrequency ablation therapy combined with hepatectomy for liver metastasis of colorectal cancer].

Radiofrequency ablation (RFA) therapy combined with hepatectomy was performed in 5 patients with synchronous liver metastases of colorectal cancer. RFA of liver metastases was performed using a Cool-tip electrode (Radionics; Burlington, MA, USA). The ablation time used in each session varied according to the tumor size and intraoperative impedance.

[A case of pathological complete response of metachronous multiple liver metastases from colorectal cancer after mFOLFOX+bevacizumab chemotherapy].

A 25-year-old man with RS rectal cancer received a radical resection of the original tumor and lymph node dissection. Oral tegafur/uracil (UFT)/Leucovorin (LV) therapy has been used for adjuvant chemotherapy, as the pathological Stage was T3N1M0, Stage IIIa. After 10 months from operation, multiple liver metastases were recognized and not resectable.

[A case of resection of synchronous multiple liver metastases from colorectal cancer after FOLFOX chemotherapy].

A 41-year-old man with multiple liver metastases from sigmoid colon cancer received a radical resection of the original tumor and 16 courses of weekly high-dose 5-FU(WHF)chemotherapy via hepatic arterial reservoir. The metastatic lesions showed stable disease(SD), and systemic chemotherapy by mFOLFOX6 was begun via CV port. After 14 courses of mFOLFOX4, abdominal CT revealed liver metastases were remarkably reduced in size.

[Gemcitabine improved QOL and survival in a case of diffuse malignant pleural mesothelioma].

Diffuse malignant pleural mesothelioma is a disease with poor prognosis, and no standard therapy for inoperable cases has been established. There are several reported trials using various anticancer drugs, but their sample sizes were small and none documented the drugs' effectiveness. Recently, some reports revealed that gemcitabine (GEM), which has been demonstrated to be effective for the treatment of non-small cell lung carcinoma, was effective in cases of diffuse malignant pleural mesothelioma.
