Radical cystectomy for locally advanced colorectal cancer with urinary bladder invasion significantly reduces the quality of life in exchange for a cure. We performed preoperative chemotherapy with FOLFOXIRI plus bevacizumab for 3 patients with locally advanced colorectal cancer with urinary bladder invasion to avoid radical cystectomy and to achieve local control for urinary bladder preservation. Grade 3 neutropenia was observed in 2 patients as an adverse reaction to the preoperative chemotherapy, but all 3 patients showed good tumor regression. All 3 patients underwent laparoscopic high anterior rectal resection and partial cystectomy, and all were able to undergo R0 resections with urinary bladder preservation. One patient had anastomotic leakage as a postoperative complication. One patient had local recurrence in the urinary bladder, and 2 had recurrence with peritoneal dissemination during their postoperative courses. Preoperative chemotherapy(FOLFOXIRI plus bevacizumab)for locally advanced colorectal cancer with urinary bladder invasion is considered to be a useful treatment option because of its potential for tumor shrinkage and bladder preservation.

A 56-year-old female was referred to our hospital for further examination and treatment because of her increasing right axillary mass for 1 year. Based on histological examination diagnosing the right axillary mass as carcinoma and radiological examination showing no evidence of distal metastasis, we decided to perform a radical resection. The patient underwent right axillary mass resection, axillary lymph node dissection, and latissimus dorsi musculocutaneous flap reconstruction. Right-sided breast cancer was diagnosed based on histopathological examination. The diagnosis was similar to that of breast cancer. The patient underwent adjunctive chemotherapy and is currently undergoing endocrine therapy. The incidence of accessory breast cancer is 0.2-0.6% among all breast cancers and is relatively rare. Postoperative adjuvant pharmacotherapy has no consensus. However, endocrine therapy, chemotherapy, and molecular target therapy are performed in cases of conventional breast cancer. Herein, we describe a case of right axillary accessory breast cancer with skin invasion successfully treated with radical resection.

The patient is a 51-year-old female with comorbidity of schizophrenia. At the age of 41, she underwent surgery for bilateral breast cancer. Both sides were of the Luminal type, with Stage ⅢC on the right and Stage 0 on the left. She started to receive adjuvant chemotherapy but it was interrupted according to her wish. Approximately 3 years ago, she developed carcinomatous pleuritis, multiple liver metastases, and bone metastases. Despite receiving chemotherapy, her condition worsened. A BRACAnalysis revealed pathogenic variants in BRCA2. Upon initiating treatment with olaparib, both her liver metastases and carcinomatous pleuritis have shown reductions, and her tumor markers have also started to decline. Approximately 5 months after treatment with olaparib, it has been possible to continue without any side effects. Olaparib has shown good results in patients with germline BRCA1/2 mutation-positive HER2-negative advanced/recurrent breast cancer who have a history of receiving anthracycline and taxane-based therapies. It was considered that even in recurrent breast cancer, the presence or absence of BRCA1/2 mutations should be actively sought even in advanced cases, and the administration of olaparib should be considered.

Objective: Although neoadjuvant chemotherapy(NAC)has been recognized as an important option for improving the clinical outcome of patients with advanced gastric carcinoma, convincing evidence that it prolongs life and brings about a good prognosis are both lacking. We retrospectively evaluated the efficacy and safety of NAC in ten patients with advanced gastric cancer., Methods: A total of ten patients with advanced gastric cancer, who received NAC with the combination of S-1 and cisplatin in our hospital from April 2008 to March 2010, were retrospectively investigated., Results: A total of 5 patients responded to neoadjuvant chemotherapy, and 2 patients showed a complete regression of the primary gastric carcinoma. Four of the 5 patients who responded had solid-type poorly-differentiated adenocarcinoma., Conclusion: NAC with the combination of S-1 and cisplatin was suggested to be effective for advanced gastric carcinoma, especially for solid-type poorly differentiated adenocarcinomas(por1).

Case 1 was a 58-year-old woman diagnosed with unresectable liver metastases from advanced rectal cancer. We performed laparoscopic low anterior resection for sigmoid cancer. As the first-line treatment, FOLFOX+bevacizumab(BV)was applied for 16 courses. The second-line treatment, FOLFIRI plus BV, was applied for four courses. However, the disease progressed with worsening liver metastases. The sequencing of K-RAS genes from the biopsy specimens of sigmoid colon cancer revealed an expression of a wild-type K-RAS. As the third-line treatment, panitumumab was applied. After 8 courses of this chemotherapy regimen, a significant reduction in the size of liver metastases was observed. Case 2 was an 81-year-old man diagnosed with unresectable liver metastases from advanced rectal cancer. We obliged the patient by performing laparoscopic rectal resection. As the first-line treatment, XELOX plus BV was applied for 10 courses. As the second-line treatment, IRIS was applied for 6 courses. However, this failed to prevent him from having a progressive disease. As the third-line treatment, panitumumab was applied for 2 courses, and a significant reduction in the size of liver metastases was observed. Our findings suggested that panitumumab has great potential for effective treatment of patients with unresectable stageIV colorectal cancer.

The patient was a 77-year-old woman with multiple liver metastases of sigmoid colon cancer. She underwent low anterior resection for sigmoid colon cancer. After surgery, she selected oral administration of UFT and LV for liver metastases and multiple lymph node metastases. After two courses, the liver metastases had markedly diminished. Thirty-two months later, liver metastases had disappeared on computer tomography. This therapy was continued for five years, and recurrences are no longer shown. Severe adverse effects were not observed. Oral anti-cancer drugs can serve as effective therapy for advanced colorectal cancer of old patients.

Patients with bone metastasis originating from gastric cancer experience complications from DIC. They are treated with anticoagulation therapy or platelet transfusion, but their prognosis is poor. Our case was a 50-year-old male who had undergone distal gastrectomy for early gastric cancer[pT1a(M)N0M0, pStage I a]ten years previously. He was admitted to our hospital complaining of backache. As a result of his examination, he was diagnosed with disseminated carcinosis of bone marrow with DIC as a postoperative recurrence of gastric cancer. The patient was treated with combination chemotherapy of S-1 and cisplatin(S-1 80 mg/body, po, day 1-21 and cisplatin 50mg/body, iv, day 8). After one course of treatment, DIC was resolved and his pain was relieved. He survived for about nine months. S-1 and cisplatin are considered to be effective for disseminated carcinosis of bone marrow.

The patient was a 56-year-old female. At the age of 35 years, she had under gone left mastectomy and axillary lymph node dissection for breast cancer. After surgery, hormonal therapy was continued for 3 years. Then, no treatment was performed. In this study, single therapy with an AI agent was started to treatbilateral supraclavicular fossa/mediastinal lymphnode metastases. After 6 months, a partial response(PR)was achieved. However, progression of the disease(PD)was noted after 1 year. Thereafter,the regimen was switched to single high-dose(120mg/day)TOR therapy. CT revealed the disappearance of the bilateral supraclavicular fossa lymphnodes and a marked reduction of the other lymphnodes. Currently, the patient is being treated, with an interval of 10 months from the start of TOR therapy.
