Introduction: This study examined the association between the use of home nursing care and the consultation time of emergency home visits among patients using home health care. Methods: Participants were recruited from three urban clinics in Japan between September 1 and November 30, 2019. Univariate analysis and multivariate negative binomial regression analysis considering institutional clusters were performed on the relationship between the two. Results: A total of 278 patients were included in the analyses. The use of home nursing care was significantly associated with a decrease in the time spent during emergency home visits in both univariate and multivariate analyses (P < 0.018 and P < 0.001, respectively). The multivariate analysis estimated the mean reduction in consultation time to be 10.3 minutes (95% confidence interval, 9.9-10.8). Conclusion: The use of home nursing care reduced the consultation time in emergency home visits. This study suggested that home nursing care can reduce the burden on physicians providing home visits, but further studies are needed to improve collaboration.

Objective: This study aimed to investigate the prognosis of patients with intermediate-risk cervical cancer and to evaluate the necessity of adjuvant therapy. Methods: We conducted a retrospective chart review of patients with stage IB–II cervical cancer who underwent type III radical hysterectomy with pelvic lymphadenectomy between 2008 and 2017. In our institution, radical hysterectomy is performed as an open surgery and not as a minimally invasive surgery, and adjuvant therapy is not administered to patients with intermediate-risk cervical cancer. The intermediate-risk group included patients with 2 or more of the following factors: tumor size >4 cm, stromal invasion >1/2, and lymphovascular stromal invasion. Intermediaterisk patients with squamous cell carcinoma were included in the I-SCC group, whereas those with endocervical adenocarcinoma, usual type, or adenosquamous carcinoma were included in the I-Adeno group. Results: There were 34 and 18 patients in the I-SCC and I-Adeno groups, respectively. The 5-year recurrence-free survival (RFS) and overall survival rates in the I-SCC group were 90.5% (95% confidence interval [CI], 85.3–95.7%) and 100% (95% CI, 100%), respectively, whereas those in the I-Adeno group were 54.9% (95% CI, 42.0–67.9%) and 76.1% (95% CI, 63.7–88.4%), respectively. Multivariate analysis revealed that endocervical adenocarcinoma, usual type, or adenosquamous carcinoma, and tumor size >4 cm had worse RFS. Conclusion The I-SCC group had good prognosis without adjuvant therapy; therefore, adjuvant therapy may be omitted in these patients. In contrast, the I-Adeno group had poor prognosis without adjuvant therapy; therefore, adjuvant therapy should be considered in their treatment.

OBJECTIVE: To treat advanced ovarian cancer, interval debulking surgery (IDS) is performed after 3 cycles each of neoadjuvant chemotherapy (NAC) and postoperative chemotherapy (IDS group). If we expect that complete resection cannot be achieved by IDS, debulking surgery is performed after administering additional 3 cycles of chemotherapy without postoperative chemotherapy (Add-C group). We evaluated the survival outcomes of the Add-C group and determined their serum cancer antigen 125 (CA125) levels to predict complete surgery. METHODS: A retrospective chart review of all stage III and IV ovarian, fallopian tube, and peritoneal cancer patients treated with NAC in 2007–2016 was conducted. RESULTS: About 117 patients comprised the IDS group and 26 comprised the Add-C group. Univariate and multivariate analyses revealed that Add-C group had an equivalent effect on progression-free survival (PFS; p=0.09) and overall survival (OS; p=0.94) compared with the IDS group. Multivariate analysis revealed that patients who developed residual disease after surgery had worse PFS (hazard ratio [HR]=2.18; 95% confidence interval [CI]=1.45–3.28) and OS (HR=2.33; 95% CI=1.43–3.79), and those who received <6 cycles of chemotherapy had worse PFS (HR=5.30; 95% CI=2.56–10.99) and OS (HR=3.05; 95% CI=1.46–6.38). The preoperative serum CA125 cutoff level was 30 U/mL based on Youden index method. CONCLUSIONS: Administering 3 additional cycles of chemotherapy followed by debulking surgery exhibited equivalent effects on survival as IDS followed by 3 cycles of postoperative chemotherapy. Preoperative serum CA125 levels of ≤30 U/mL may be a useful predictor of achieving complete surgery.

OBJECTIVE: This study aimed to evaluate the efficacy of magnetic resonance (MR) imaging in differentiating between cutaneous basal cell carcinoma (cBCC) and cutaneous squamous cell carcinoma (cSCC) in the head and neck region.MATERIALS AND METHODS: Among patients with cutaneous head and neck cancers, 14 with primary cBCCs and 15 with primary cSCCs with a histologic tumor height of ≥ 4 mm underwent MR examinations; the findings were then examined for correlations.RESULTS: cBCCs (71%) occurred more frequently on the nose than cSCCs (13%) (p < 0.01). The maximum diameter (23.5 ± 7.2 mm vs. 12.7 ± 4.5 mm; p < 0.01) and diameter-to-height ratio (2.8 ± 0.9 vs. 1.7 ± 0.4; p < 0.01) were significantly greater in cSCCs than in cBCCs. Superficial ulcer formation (67% vs. 21%; p < 0.05), protrusion into the subcutaneous tissue (60% vs. 21%; p < 0.05), ill-demarcated deep tumor margins (60% vs. 7%; p < 0.01), and peritumoral fat stranding (93% vs. 7%; p < 0.01) were more frequently observed in cSCCs than in cBCCs. Intratumoral T2-hyperintense foci (57% vs. 13%; p < 0.05) were more frequently observed in cBCCs than in cSCCs.CONCLUSION: cBCCs predominantly occurred on the nose with intratumoral T2-hyperintense foci, whereas cSCCs predominantly exhibited a flattened configuration, superficial ulcer formation, protrusion into the subcutaneous tissue, ill-demarcated deep tumor margin, and peritumoral fat stranding.

Objective: Folate receptor α (FRα) is a membrane protein expressed in various solid tumors but has limited expression in normal cells. Therefore, FRα is an attractive target for cancer treatment. This study aimed to investigate the relationship between FRα expression and the clinicopathological characteristics and survivals of cervical cancer. Methods: This retrospective study included patients with cervical cancer who underwent primary surgery between 2000 and 2020 at our institution. Immunohistochemical staining of FRα was performed using an anti-folate-binding protein/FBP antibody. FRα-positive staining was defined as ≥5% of tumor staining and FRα-high as ≥50% tumor staining with ≥2+ intensity. The association between FRα expression and survival was assessed using multivariate Cox regression analysis, adjusting for established prognostic factors. Results: Overall, 123 patients were identified, and 140 tumor samples, including 17 paired primary and metastatic samples, were evaluated. As histological types, 67 patients had squamous cell carcinoma (SCC), and 56 patients had non-SCC. All primary tumors were FRα-positive. High FRα expression was observed in 25% of the cases and differed according to histology (SCC vs. non-SCC, 14.9% vs. 37.5%, p=0.004). FRα expression was significantly higher in metastatic tumors than in primary (170 [IQR, 140–205] vs. 125 [IQR, 110–150], p=0.0006). High FRα expression was significantly associated with worse overall survival (hazard ratio, 6.73; 95% confidence interval, 2.21–20.53; p=0.001). Conclusion In cervical cancer, FRα expression was elevated in metastatic tumors and high expression was associated with a worse prognosis. Our study supports the development of FRα-targeted therapy for advanced cervical cancer.

Background: The anti-programmed death 1 (PD-1) antibody has led to durable clinical responses in a wide variety of human tumors. We have previously developed the caninized anti-canine PD-1 antibody (ca-4F12-E6) and evaluated its therapeutic properties in dogs with advance-staged oral malignant melanoma (OMM), however, their therapeutic effects on other types of canine tumors remain unclear. Objective: The present clinical study was carried out to evaluate the safety profile and clinical efficacy of ca-4F12-E6 in dogs with advanced solid tumors except for OMM. Methods: Thirty-eight dogs with non-OMM solid tumors were enrolled prospectively and treated with ca-4F12-E6 at 3 mg/kg every 2 weeks of each 10-week treatment cycle. Adverse events (AEs) and treatment efficacy were graded based on the criteria established by the Veterinary Cooperative Oncology Group. Results: One dog was withdrawn, and thirty-seven dogs were evaluated for the safety and efficacy of ca-4F12-E6. Treatment-related AEs of any grade occurred in 13 out of 37 cases (35.1%).Two dogs with sterile nodular panniculitis and one with myasthenia gravis and hypothyroidism were suspected of immune-related AEs. In 30 out of 37 dogs that had target tumor lesions, the overall response and clinical benefit rates were 6.9% and 27.6%, respectively. The median progression-free survival and overall survival time were 70 days and 215 days, respectively. Conclusions The present study demonstrated that ca-4F12-E6 was well-tolerated in nonOMM dogs, with a small number of cases showing objective responses. This provides evidence supporting large-scale clinical trials of anti-PD-1 antibody therapy in dogs.

Objective: The purpose of this survey was to estimate the prevalence of viral load (VL) suppression and emergence of HIV drug resistance (HIVDR) among individuals receiving antiretroviral therapy (ART) for 36 months or longer in Viet Nam using a nationally representative sampling method. Methods: The survey was conducted between May and August 2014 using a two-stage cluster design. Sixteen ART clinics were selected using probability proportional to proxy size sampling, and patients receiving ART for at least 36 months were consecutively enrolled. Epidemiological information and blood specimens were collected for HIV-1 VL and HIVDR testing; HIVDR was defined by the Stanford University HIVDR algorithm. Results: Overall, 365 eligible individuals were recruited with a mean age of 38.2 years; 68.4% were men. The mean time on ART was 75.5 months (95% confidence interval [CI]: 69.0–81.9 months), and 93.7% of the patients were receiving non-nucleoside reverse transcriptase inhibitor-based regimens. Of the 365 individuals, 345 (94.7%, 95% CI: 64.1–99.4%) had VL below 1000 copies/mL and 19 (4.6%, 95% CI: 2.8-–7.5) had HIVDR mutations. Discussion Our nationally representative survey found a high level of VL suppression and a low prevalence of HIVDR among individuals who received ART for at least 36 months in Viet Nam. Continued surveillance for HIVDR is important for evaluating and improving HIV programs.

The patient was a 52-year-old woman who had undergone laparoscopic colectomy with lymph node dissection and inferior mesenteric artery preservation for cancer of the descending colon. Functional end-to-end anastomosis was performed using a linear stapler. Colonoscopy at the 1-year follow-up revealed a type 2 tumor at the anastomotic site. She was diagnosed with anastomotic recurrence. We performed laparoscopic high anterior resection with inferior mesenteric artery dissection. Rectal resection preceded mobilization of the mesocolon because of severe adhesion around the anastomotic site. Laparoscopic surgery for anastomotic site recurrence is an option under the condition that the initial surgery was laparoscopic.

A 14-year-old girl (Case 1) with respiratory distress during exercise was referred to our department after a pancreatic mass was detected by computed tomography (CT). Contrastenhanced CT scan showed a low-density mass measuring 2.5 × 2 cm in the body of the pancreas. Low signal intensity was seen on T1-weighted magnetic resonance imaging (MRI) and high signal intensity on T2-weighted MRI. We suspected solid-pseudopapillary neoplasm (SPN) of the pancreas and performed laparoscopy-assisted spleen-preserving distal pancreatectomy. The postoperative course was uneventful, and she was discharged on postoperative day 13. A 15-yearold girl (Case 2) with abdominal pain and fever was referred to our department after an abdominal cystic mass was detected by ultrasound examination. Contrast-enhanced CT showed a 4-cm well-circumscribed mass. Higher signal intensity was seen on T2-weighted MRI. We suspected SPN of the pancreas and performed laparoscopic spleen-preserving distal pancreatectomy. The postoperative course was uneventful, and she was discharged on postoperative day 8. Laparoscopic or laparoscopy-assisted surgery should be considered for SPN of the pancreas.
