An oral anticancer drug, TS-1, enabled a patient with advanced gastric cancer with Virchow's metastasis to receive curative resection

We encountered a patient with advanced gastric cancer, with Virchow's lymph node metastasis, who subsequently underwent curative resection after neoadjuvant chemotherapy with the newly developed oral anticancer drug, TS-1. The patient was a 67-year-old woman who had a type 2 tumor in the middle third of the stomach, and Virchow's lymph node metastasis, which was diagnosed by fine-needle aspiration cytology; she also had swollen paraaortic lymph nodes. Curative resection was considered impossible, and TS-1 (100 mg/day) was administered for 28 days in one course, mainly in the outpatient clinic. Although grade 2 stomatitis interrupted the therapy on day 21 of the second course and on day 7 of the third course, the type 2 tumor showed marked remission (partial response; PR) and the metastasis in the Virchow's and paraaortic lymph nodes had completely disappeared after the third course (complete response; CR). Eleven weeks after the completion of the TS-1 treatment, total gastric resection with D3 lymph node dissection was performed. Histopathological examination revealed tumor involvement only in the mucosal and submucosal layers of the stomach and the no. 4d lymph node. Most of the tumor was replaced with fibrosis with granulomatous change in the muscularis propria of the stomach and in the no. 3, no. 6, and no. 7 lymph nodes. This may be the first report of a patient with advanced gastric cancer with Virchow's lymph node metastasis who successfully received curative resection following neoadjuvant chemotherapy with a single oral anticancer drug.

Uncooked cornstarch treatment for hepatic phosphorylase kinase deficiency

A 5-year-old boy with short stature, hepatomegaly and motor weakness due to hepatic phosphorylase kinase deficiency is described. Laboratory data showed mild hypoglycaemia and metabolic acidosis, hepatic dysfunction, and a low insulin-like growth factor-I level. Mild hypoglycaemia, marked ketosis and insufficient growth hormone secretion were revealed at night. Serum total and free carnitine levels were low and the acyl/total carnitine ratio was high. Urinary acylcarnitine profile using fast atom bombardment and tandem mass spectrometry showed increased excretion of acetylcarnitine and dicarboxylylcarnitines. These endocrinological and metabolic abnormalities and clinical symptoms were improved with uncooked cornstarch treatment.     

Prognosis of primary testicular seminoma: a report on 57 new cases

Most urologists perform adjuvant radiation therapy for stage 1 (TxN0M0) testicular seminoma after orchiectomy, although the majority of patients with clinical stage 1 seminoma do not have occult metastases and therefore do not require elective nodal irradiation. However, there are currently no clinical or histological parameters that can be used to distinguish patients who need radiation therapy from those who do not. We reported previously that estimates of volume-weighted mean nuclear volume (MNV) were a better predictor of the prognosis of prostate cancer and renal cell carcinoma than subjective histological grading. Here, we examined the usefulness of estimation of MNV for predicting the prognosis of primary testicular seminoma. A retrospective study of 57 patients with testicular seminoma diagnosed between April 1981 and March 1997 at Kobe City General Hospital was performed. Unbiased estimates of MNV data were compared for prognostic value with the level of beta-human chorionic gonadotropin (beta-HCG), alpha-fetoprotein (AFP), alkaline phosphatase (ALP), and lactate dehydrogenase (LDH). Fifty patients were stage 1 (TxNoMo), and 7 patients were stage 2 (TxN1-2M0). All patients received orchiectomy, followed by radiation therapy. Estimates of MNV of stage 2 patients were significantly larger than that of stage 1 patients (P = 0.0142). Although the LDH level was also significantly higher in stage 2 (P = 0.001), there were no significant differences between stages 1 and 2 with respect to beta-HCG (P = 0.997), ALP (P = 0.226), and AFP (P = 0.467). Multivariate logistic regression analysis revealed that the estimate of MNV was the only variable predicting lymph node metastasis (P = 0.0315). In stage 1 patients, only the estimate of MNV was significantly correlated with progression-free survival (P = 0.0118). These findings indicate that the estimate of MNV may be an important prognostic indicator for testicular seminoma. Estimates of MNV may also be useful for excluding patients from surveillance protocols.     

Relationship between surgical procedure and spontaneous urination after rectal cancer surgery

OBJECTIVE: The aim of this study was to determine the relationship between surgical procedures and spontaneous urination after rectal cancer surgery. METHODS: We reviewed the time of removal of the Foley catheter in 91 patients with middle and lower rectal cancer who had undergone curative surgery, either abdominoperineal resection (APR) or sphincter-preserving operation (SPO), without pelvic lymphadenectomy (PL). We also reviewed the time of catheter removal in 40 rectal cancer patients who had undergone one of four types of autonomic nerve preserving (ANP) operations. RESULTS: The mean time of removal of the catheter was 7.3 postoperative days (POD) in patients who underwent APR and 3.1 POD in patients who underwent SPO (p = 0.01). The mean time of removal in patients who underwent ANP for the entire plexus without PL (type 1a) was 6.7 POD. It was 5.6 POD in ANP for the entire plexus with PL (type 1b), 13.8 POD in ANP for bilateral pelvic plexus with PL (type 2) and 15.8 POD in ANP for unilateral pelvic plexus with PL (type 3). CONCLUSION: The type of operation and the volume of preserved nerves could be influential factors in the time to removal of the Foley catheter after rectal cancer surgery.     

Evaluation of Blood Flow by Color Doppler Sonography in Free Jejunal Interposition Grafts for Cervical Esophageal Reconstruction

The failure of the vascular anastmoses is a devastating complication in free jejunum transplantation. We used color Doppler sonography to estimate blood flow in free jejunal grafts in 21 patients who underwent radical pharyngoesophagectomy. Fast Fourier transform (FFT) analysis of blood flow, the pulsatility index (PI) as a measure of peripheral vascular resistance, and thickening of the graft wall were evaluated for predictive value. The arterial wave patterns were classified into three types based on systolic–diastolic differences and magnitude of flow. Type I was physiologic flow, type III overtly pathologic, and type II intermediate. The three patients who required vascular reanastomoses intraoperatively had a type II pattern that degenerated to type III within 15 minutes. The PI increased to 3.5 to 4.5 over 1 hour. In the one patient who required retransplantation, the wave pattern became type III by 18 hours and had disappeared by 24 hours, at which point the PI could not be measured. Jejunal thickening increased from 1.0 mm to 5.0 mm after 24 hours, even in healthy grafts. Monitoring blood flow during the 24 hours after surgery is critical. A type III wave pattern or a PI >2.5 is an indication for reexploration. Doppler sonography offers a noninvasive way to measure blood flow in jejunal grafts semiquantitatively and can predict free jejunal graft failure.
