Gastric carcinoma (GC) is the fifth most common malignancy worldwide but the third leading cause of cancer death, and surgery remains the only curative treatment option. Prognosis of patients with liver metastases from gastric carcinoma (LMGC) is poor, and the optimal treatment of metastatic gastric cancer remains a matter of debate. In 2002, a 53-year-old male patient with GC and synchronous oligometastatic lesion in liver VIII segment underwent a total gastrectomy combined with metastasectomy. The pathologic diagnosis was stage IV gastric adenocarcinoma (pT3N2M1), which was treated with adjuvant chemotherapy (cisplatin, epirubicin, leucovorin, and 5-fluorouracil)...

PURPOSE: To review the use of diagnostic breast imaging and outcomes for symptomatic male patients. METHODS: We retrospectively evaluated 122 males who underwent diagnostic imaging for breast symptoms at our academic center. RESULTS: The majority (94%) of cases had negative or benign imaging, with gynecomastia being the most common diagnosis (78%). There were two malignancies, both of which had positive imaging. Fifteen patients underwent percutaneous biopsy, and over half (53%) were palpation-guided biopsies initiated by the referring clinician despite negative imaging...

Lupus mastitis is an uncommon manifestation of systemic lupus erythematosus (SLE) that affects the subcutaneous fat in the breast, much like lupus panniculitis, but additionally involves the mammary gland. We report on two women for whom lupus mastitis was the initial manifestation of SLE and provide a literature review of 34 additional cases reported in the Anglo-Saxon and French literature since 1971, making this the largest review to date. Lupus mastitis (LM) can manifest clinically as subcutaneous masses that may be painful, or may present cutaneous involvement such as thickening and discolouration...

BACKGROUND: Although surgical resection is the only curative treatment for gallbladder cancer (GBC), concomitant peritoneal dissemination is considered far beyond the scope of resection. We report a long-term survivor with a residual GBC with multiple peritoneal disseminations who underwent an extended resection after effective chemotherapy. CASE PRESENTATION: A 59-year-old male underwent an open cholecystectomy for Mirizzi syndrome at a local hospital. Because of severe inflammation, the gallbladder was perforated during surgery, ending in a piecemeal resection...

Skeletal-related events in patients with metastatic bone disease include intractable severe pain, pathologic fracture, spinal cord and nerve compression, hypercalcemia and bone marrow aplasia. In patients with breast cancer, the skeleton is the most frequent site for metastases. Treatment options for metastatic bone disease in these patients include bisphosphonates, chemotherapeutic agents, opioids, hormonal therapy, minimally invasive/interventional and surgical techniques. Interventional oncology techniques for breast cancer patients with bone metastases include diagnostic (biopsy) and therapeutic (palliative and curative) approaches...

We describe a rare case of secondary breast carcinoma after chronic myeloid leukemia (CML) in a 56-year-old woman. The patient was treated with hydroxyurea and imatinib for CML and achieved complete remission (she has since been taking imatinib as the maintenance therapy). Four years later, the patient noticed a firm and painless lump in the left breast, which was diagnosed as ductal carcinoma in situ based on a percutaneous biopsy of the mass. Simple resection and sentinel lymph node biopsy of the left breast were then performed...

OBJECTIVE: Although driver mutation status is crucial to targeted therapy decision-making in non-small cell lung cancer (NSCLC), due to unavailable or inadequate biopsies, there are still many patients with unknown mutation status. A promising way to solve this problem is liquid biopsy, such as cell-free DNA (cfDNA) in peripheral blood. Additionally, due to the little amount of cfDNA, detecting methods with high sensitivity, specificity and economy are required in clinical practice. Here, we explored the feasibility of Competitive Allele-Specific TaqMan® PCR (CastPCR) detecting driver mutations in cfDNA from plasma in lung adenocarcinoma patients...

Computed tomography (CT)-guided percutaneous fine needle biopsy is a common method for lung biopsy. The objective of this study was to investigate factors affecting the accuracy and safety of CT-guided percutaneous lung biopsy of nodules ≤30 mm in diameter. Between January 2013 and March 2014, 155 patients underwent a CT-guided percutaneous biopsy procedure on an intrapulmonary solitary nodule measuring ≤30 mm in diameter. Prospectively collected data were retrospectively reviewed and examined for the influence of clinical and pathological characteristics (age, gender, smoking status, adhesion of nodule to the pleura, puncture depth, nodule size and time of biopsy) on the accuracy of biopsy and incidence of pneumothorax and hemorrhage...
