RESUMO
A 52-year-old female with stage â £, bilateral, HER2-positive, breast cancer as well as bilateral axillary lymph node(LN) metastasis and bilateral pulmonary metastasis was administered trastuzumab plus pertuzumab plus docetaxel as a standard chemotherapy. After this treatment the right breast cancer, right axillary LN metastasis, and bilateral pulmonary metastases contracted, while the left breast cancer and left axillary LN metastasis expanded. Trastuzumab emtansine was then administered, and the left axillary LN metastasis contracted, however, the left breast cancer expanded, resulting in marked breast engorgement. When trastuzumab deruxtecan(T-DXd)was administered, the left breast cancer contracted for the first time during the overall treatment process, and the signs of breast inflammation disappeared. Other lesions showed no recrudescence. T-DXd was administered seven times, and, at the stage of maximum contraction during the treatment period, a total left mastectomy and left axillary LN dissection were performed. Pathological examination then confirmed that tumor cells were no longer present in the left breast and left axillary LN. In this case T-DXd was highly effective for the local treatment of intractable, HER2-positive, breast cancer.

BACKGROUND: Survival benefit of liver resection for noncolorectal liver metastases (NCRLM) remains to be defined. METHODS: This multicenter, retrospective cohort analysis included consecutive patients with NCRLM whose primary tumor and all metastases were treated with curative intent between 2000 and 2013. The primary endpoint was 5-year overall survival. Clinicopathological factors that affected prognoses were identified using multivariate Cox regression analyses and were included in a predictive model. RESULTS: Data for 205 patients were analyzed. The three most common primary tumor sites were stomach (39%), pancreas (13%), and urinary tract (10%), with adenocarcinomas the main pathology (52%). R0 resection was achieved in 85%, and the overall survival at 5 years was 41%. In the multivariate analysis, synchronous liver metastases, R1/2 resection, and adenocarcinomas and other carcinomas (with gastrointestinal stromal tumors, neuroendocrine tumors G1/G2, and sarcomas set as the reference group) were independent negative indicators of overall survival. A predictive model effectively stratified the NCRLM patients into low-, intermediate-, and high-risk groups with overall 5-year survival rates of 63%, 38%, and 21%, respectively (P < 0.001). CONCLUSIONS: Patients who underwent curative resection for metachronous disease and favorable tumor pathology are expected to have better survival in the NCRLM cohort.

BACKGROUND: Bleeding remains an important intraoperative complication in patients who undergo hepatectomy. It is generally believed that a reduction in central venous pressure will decrease bleeding from the hepatic venous system. To our knowledge, however, no study has compared the effectiveness of these techniques for controlling bleeding. So we compared the effectiveness of central venous pressure control techniques, such as infrahepatic inferior vena cava clamping, changes in surgical position of the patient, and hypoventilation anesthesia, for lowering central venous pressure. METHODS: The study group comprised 50 patients who underwent hepatectomy in our department from 2012 through 2013. A central venous catheter was inserted into the right internal jugular vein, and the tip was placed in the superior vena cava. A transducer was placed along the mid-axillary line of the left side of the chest. After opening the abdomen, changes in central venous pressure were measured during inferior vena cava clamping, the reverse Trendelenburg position, the Trendelenburg position, and hypoventilation anesthesia. The inclination relative to the transducer, as measured with an inclinometer, was -10 degrees for the Trendelenburg position and +10 degrees for the reverse Trendelenburg position. The tidal volume was set at 10 mL/kg during conventional anesthesia and 5 mL/kg during hypoventilation anesthesia. RESULTS: The mean central venous pressure was 8.0 cm H(2)O in the supine position during conventional anesthesia, 5.0 cm H(2)O during inferior vena cava clamping, 5.6 cm H(2)O during reverse Trendelenburg position, 10.6 cm H(2)O during Trendelenburg position, and 7.6 cm H(2)O during hypoventilation anesthesia. The mean central venous pressure during inferior vena cava clamping and reverse Trendelenburg position was significantly lower than that during supine position (P = 0.0017 and P = 0.0231, respectively). The mean central venous pressure during hypoventilation anesthesia was not significantly lower than that during supine position (P = 0.9934). Mean systolic blood pressure was significantly decreased during inferior vena cava clamping (P = 0.0024), but not during reverse Trendelenburg position (P = 0.6344). CONCLUSIONS: Reverse Trendelenburg position decreased central venous pressure without significantly decreasing the systolic blood pressure, suggesting that it is possible to perform hepatectomy with reverse Trendelenburg position more safely than with inferior vena cava clamping.

BACKGROUND: The novel technique of virtual hepatectomy is useful for evaluation of the portal territory of the liver, since this software program includes functions for liver surgery planning. We evaluated the accuracy of virtual hepatectomy for anatomical hepatectomy. METHODS: Between 2010 and 2011, 92 patients with liver tumors underwent virtual hepatectomy preoperatively. The predicted liver volume was compared with the actual liver volume among patients who underwent anatomical sectionectomy, segmentectomy, and hemihepatectomy. RESULTS: Ninety of 92 patients underwent anatomical hepatectomy on the basis of virtual hepatectomy. According to the surgical procedure, the predicted liver resection volume showed a strong correlation with the actual liver volume in patients who underwent sectionectomy (r = 0.985, p < 0.0001, n = 44, median error rate 9 %), segmentectomy (r = 0.949, p < 0.0001, n = 17, median error rate 12 %), and hemihepatectomy (r = 0.967, p < 0.0001, n = 29, median error rate 7 %). CONCLUSIONS: The novel technique of virtual hepatectomy is useful for evaluation of the portal territory for anatomical sectionectomy, segmentectomy, and hemihepatectomy.

PURPOSE: Radiofrequency ablation(RFA) is minimally invasive and is easy to perform. In the RFA procedure, puncture and passing of the electrical current are painful. Therefore, some facilities use general anesthesia for RFA. In order to evaluate the use of general anesthesia for RFA of hepatocellular carcinoma, a questionnaire survey was conducted. METHODS: With the cooperation of Tokyo liver-tomo-no-kai(Tokyo Liver Association), a questionnaire survey was conducted for patients who underwent RFA. In the survey, data on the following were obtained "type of anesthesia used", "number of RFA treatment points", "duration of treatment", "length of impact of pain", and "if you need to receive RFA treatment again, how would you feel about this." RESULTS: The ratio of local anesthesia (LA) to general anesthesia (GA) was 113:24. The ratios of the numbers of patients who felt pain to those who felt no pain were 64:49 (LA) and 0:24 (GA). The ratios of the patients who wished to not receive RFA again to the patients who were comfortable with receiving RFA were 65:45 (LA) and 4:20 (GA). CONCLUSION: GA achieves better pain control compared to LA, and the patients who receive GA have greater tolerance of RFA.
