RESUMEN
The 208 trial showed that lenvatinib has a significant antitumor effect on unresectable anaplastic thyroid cancer(ATC). Herein, we present a retrospective review of data from 7 patients with unresectable ATC who received lenvatinib in our hospital between May 2015 and October 2016. Two patients were men and 5 were women. The median age was 78(range, 72-85)years, and 1 patient had Stage IV A disease, 1 had Stage IV B, and 5 had Stage IV C at diagnosis, respectively. Three patients experienced a partial response and 1 patient experienced stable disease. The response rate was 43%, and the disease control rate was 57%. The median progression-free survival(PFS)was 4.1(range, 1.1-12.2)months. Grade 3 and Grade 4 gastrointestinal hemorrhage were observed in 2patients and Grade 3 anorexia was observed in 1 patient. Further clinical research seems to be needed to establish a treatment strategy involving lenvatinib for ATC.

A 73-year-old woman had undergone mastectomy for left breast cancer. One year later, bone metastasis was detected. After 7 years, the patient experienced epigastric discomfort, and gastrointestinal endoscopy showed stenosis of the pylorus and enlarged gastric folds. Stomach cancer was suspected at first, but gastric metastasis of breast cancer was diagnosed on the basis of endoscopic reexamination and computed tomography(CT)images. The patient could not drink water, and therefore, gastrointestinal stenting was performed, which facilitated ingestion to some extent. However, at the same time, an elevated serum carcinoembryonic antigen(CEA)level and jaundice were observed. Therefore, biliary tract stenosis due to carcinomatous peritonitis was diagnosed. We attempted to treat the jaundice with endoscopic retrograde cholangiopancreatography( ERCP)or percutaneous transhepatic cholangiography(PTCD), but the treatment was not successful, and an increase in ascites was noted. Accordingly, gemcitabine was administered as systemic therapy. As a result, ascites decreased and jaundice improved. Patients with gastric metastasis of breast cancer have poor quality of life(QOL)because of difficulties in ingestion or vomiting, and poor prognoses, because of frequent concurrent carcinomatous peritonitis. We experienced a case of gastric metastasis and carcinomatous peritonitis, and were able to improve the patient's QOL by gastrointestinal stenting and gemcitabine administration.

We retrospectively investigated the efficacy and toxicity of lapatinib plus capecitabine in 45 HER2-positive breast cancer patients. The median number of treatment courses was 6(1-22). Brain metastasis developed in 18 cases(40%), and 19 cases(42.2%)had received previous capecitabine treatment for metastatic breast cancer. The objective response rate(ORR=CR+PR)was 22.2%(10/45), and clinical benefit rate(CR+PR+long SD=24w)was 46.7%(21/45).The median time to progression(TTP)was 24.9 weeks(95% CI: 15.2 -34.6 ), and the median overall survival(OS)was 78.1 weeks(95% CI: 55.7 -100.5)in all 45 cases. The median TTP was significantly longer in patients who had not received capecitabine previously(30 vs 16 weeks, 95% CI: 16.3 -43.7, p=0.0051 ). There was no statistical difference in median OS associated with previous capecitabine exposure(42.7 weeks, 95% CI: 21.4 -64, p=0.057 ). The median TTP was significantly longer in patients who received less than 2 treatment regimens with trastuzumab for MBC rather than 3 regimens more(27.3 vs 16 weeks, p=0.0257 ), but there was no statistical difference in median OS(81 vs 40.9 weeks, p=0.26 ). Lapatinib in combination with capecitabine is likely more useful in patients who are naive to capecitabine, who received less than two regimens for metastatic breast cancer.

BACKGROUND: Non-functioning parathyroid carcinoma is a rare disease that is difficult to distinguish from other diseases based on the lack of hyperparathyroidism. This is a report of non-functioning parathyroid carcinoma diagnosed by reverse transcription polymerase chain reaction (RT-PCR) targeting parathyroid hormone (PTH) messenger RNA. CASE PRESENTATION: The patient is a 67-year-old male who visited our hospital for the chief complaint of hoarseness. A 5-cm mass was observed in the right lobe of the thyroid gland, and poorly differentiated thyroid carcinoma was suspected according to the fine-needle biopsy results. The laboratory data for thyroid functions, thyroglobulin, anti-thyroglobulin antibodies, calcium, phosphorus, and intact-PTH were all within the normal range. Right recurrent nerve paralysis was observed preoperatively. The patient was diagnosed with poorly differentiated thyroid carcinoma, and total thyroidectomy and central node dissection with partial resection of the right recurrent nerve and esophageal muscle were performed. The pathological findings revealed atypical cells containing clear cells in solid and alveolar structures with broad fibrosis. Mitosis, focal coagulative necrosis, and vascular and capsular invasions were observed. A slightly positive PTH immunohistochemical stain was noted, whereas the RT-PCR results were positive. We finally diagnosed this tumor as non-functioning PTC. No distant metastasis occurred, and the patient is still alive. CONCLUSIONS: This is a report of a patient with non-functioning parathyroid carcinoma, which is clinically very rare. We diagnosed this tumor as non-functioning parathyroid carcinoma using RT-PCR for PTH mRNA.
