RESUMO
BACKGROUND: The actual situation of oral care and oral troubles for patients with gastric cancer received chemotherapy is not clear. METHODS: Questionnaire survey in the form of oral questions was performed for patients with gastric cancer who received chemotherapy from December 2021 to February 2022. The relevance between the survey results and background factors was examined using the χ2 test. RESULTS: We performed the questionnaire survey for 36 patients. Of the 36 patients, 29 patients received dental check-up before starting chemotherapy. Fourteen of the 29 patients(48%)continued the dental check-up. Of 14 patients who continued the dental check-up, 9 patients were 65 years or older, while 14 of 15 patients who discontinued the dental check-up were 65 years or older. Continuity of dental check-up was low among the elderly patients. The rate of dysgeusia were 78 vs 30% in the patients who adopted and who did not adopt oral care other than toothbrushing(p=0.01). The frequency of oral troubles was dysgeusia(47%), stomatitis(42%), and dry mouth(36%). The severity of the oral troubles was, in order, dysgeusia, dry mouth, and pain. The most common side effect due to chemotherapy causing decreased food intake was dysgeusia. CONCLUSIONS: Dysgeusia was the most frequent and severe oral trouble.

BACKGROUND: According to the sixth Gastric Cancer Treatment Guideline, the regimen included nab-paclitaxel(nab-PTX) is a conditional recommendation as second-line treatment for advanced gastric cancer. However, the selection criteria of nab-PTX is not clear. METHOD: Questionnaire survey as narrative approach on the problems of paclitaxel premedication, the symptoms due to paclitaxel containing alcohol, and infusion time was conducted for patients who had been treated with paclitaxel. RESULTS: Thirty-six patients answered the questionnaire. Nonelderly patients(<65 years)or patients without comorbid medications complained of dissatisfaction with the inconvenience due to premedication significantly more than elderly patients(≥65 years)or patients with comorbid medications. Females or nonelderly patients were significantly more troubled by sleepiness due to premedication than males or elderly patients. Eight out of 11 patients who had visited hospital by driving a car for first-line treatment were troubled by prohibition of driving on the day of treatment. Thirty out of 36 patients answered that they would feel benefits from 30-minutes shortening of infusion time. CONCLUSION: Questionnaire survey suggests that we may select the patients for nab-PTX properly by clarifying the inconvenience of daily life associated with premedication, the way of transportation for visiting hospital, and the benefits by shortening of infusion time.

BACKGROUND: Recent developments in the field of companion diagnosis and molecular-targeting therapeutic agents have helped in developing treatments targeting human epidermal growth factor receptor 2 (HER2) in gastric cancer (GC) and esophagogastric junction cancer (EGJC), and the importance of accurate diagnosis of HER2 expression is increasing. However, the HER2-positivity rate significantly differs among reports in GC and EGJC, and factors that affect HER2-positivity require elucidation. METHODS: The present study retrospectively examined factors related to HER2-positivity in a single institution, including age, sex, body mass index, the American Society of Anesthesiologists physical status, tumor information, and surgery information, including time to specimen processing. RESULTS: Our study included 165 patients tested for HER2 using GC and EGJC surgery specimens among the 1,320 patients who underwent gastrectomy from January 2007 to June 2022. In total, 35 (21.2%) and 130 (78.8%) patients were HER2-positive and -negative, respectively. Multivariate analysis revealed that intestinal type (odds ratio [OR]: 3.41, 95% confidence interval [CI]: 1.44-8.09, p = 0.005), pM1 (OR: 3.99, 95% CI: 1.51-10.55, p = 0.005), and time to specimen processing of < 120 min (OR: 2.65, 95% CI: 1.01-6.98, p = 0.049) were independent factors that affected HER2-positivity. CONCLUSIONS: The outcomes of the present study indicated that intestinal type, pM, and time to specimen processing are important factors affecting HER2-positive rates in GC and EGJC. Therefore, the risk of false-negative HER2 results may be reduced by decreasing the time required to process the resected specimen. Additionally, accurate diagnosis of HER2 expression may increase the opportunity to administer molecular-targeted drugs that can expect therapeutic effects to patients appropriately. TRAIL REGISTRATION: Retrospectively registered.

BACKGROUND: Although pancreatoduodenectomy is recommended as a radical surgery for duodenal carcinoma, it has been reported that pancreatoduodenectomy in elderly patients has a high risk of surgical complications. CASE PRESENTATION: A man in his 80's was diagnosed with advanced duodenal carcinoma, presenting with anemia(Hb 5.4 g/dL). Computed tomography scanning showed wall thickening in the descending leg of the duodenum, pancreatic invasion was suspected, and clinical diagnosis was Stage â ¡B(cT4N0M0). Although radical surgery was possible, the patient refused surgery considering the risks of surgical complications. The gastroduodenal bypass surgery was performed to control bleeding, and the patient was treated with S-1 plus oxaliplatin(SOX; S-1 100 mg/body, days 1-14; oxaliplatin 100 mg/m2, day 1 q21 days). After 6 courses of the SOX regimen, the wall thickening of duodenum disappeared, and SOX was switched to S-1 monotherapy (S-1 100 mg/body, days 1-28, q42 days)according to Grade 2 thrombocytopenia and decreased performance status. After 11 courses of S-1, upper gastrointestinal endoscopy showed that the tumor had disappeared, the biopsy of duodenum showed no evidence of malignancy, and chemotherapy was terminated. The patient has been followed up for 7 months without recurrence. CONCLUSIONS: SOX for elderly patient showed efficacy against hemorrhagic duodenal carcinoma.

The patient was a 78-year-old woman. She presented with anemia and a positive fecal occult blood test. Endoscopic findings revealed type 3 advanced gastric cancer. As it had metastasized to the para-aortic lymph node(PALN: No. 16a2 lat), it was diagnosed as gastric cancer at cardia cT4aN1(No.1)M1(No.16a2 lat), cStage â £. She was administered S-1, oxaliplatin, and nivolumab(SOX plus Nivo)therapy as a first-line treatment. SOX plus Nivo resulted in a remarkable reduction of the lymph nodes, which were PR. After 3 courses of chemotherapy, a laparoscopic proximal gastrectomy was performed, with D2 plus No. 16a2 int/lat lymph nodes dissection as conversion surgery. Histopathological examination was pT3N0M0, and R0 resection was pStage â ¡A. She was discharged at POD21 and started S-1 from POD69. The patient is alive with no signs of recurrence 10 months postoperatively.

Bulky N+ gastric cancer has a poor prognosis. The results of JCOG0405 showed the efficacy of neoadjuvant chemotherapy with S-1 plus cisplatin combination therapy for Bulky N+ gastric cancer. JLSSG0901 demonstrated the safety and efficacy of laparoscopic surgery for advanced gastric cancer. But the safety of laparoscopic surgery for locally advanced and extensive nodal metastasis cancer(T4b, para-aortic lymph node metastasis)is not apparent. After DOS therapy, we performed total laparoscopic gastrectomy, DP(distal pancreatectomy), D2+ #16a2/b1 lat, and Roux-en-Y reconstruction, and histopathological results showed that the aortic lymph node metastasis disappeared. We controlled extensive lymph node metastasis using preoperative triplet chemotherapy. Laparoscopic surgery after preoperative chemotherapy for Bulky N+ gastric cancer can be a treatment option because we performed laparoscopic resection and para-aortic lymph node dissection with no complications, including pancreatic complications.

We report our experience with atezolizumab plus bevacizumab for unresectable hepatocellular carcinoma. METHODS: Fourteen patients with unresectable hepatocellular carcinoma treated with atezolizumab plus bevacizumab at our department were retrospectively evaluated for antitumor efficacy and adverse events. RESULTS: Age ranged from 66-91 years(median 77.5 years), 11 males and 3 females, number of doses ranged from 2-26(median 13), and observation period ranged from 31-790 days (median 427 days). Antitumor efficacy was CR in 3 patients, PR in 3, SD in 6, and PD in 2. One patient with PD died 650 days after the start of treatment, but the others are still alive. Adverse events included proteinuria in 9 patients who discontinued bevacizumab, hypothyroidism requiring levothyroxine sodium hydrate in 7 patients, dermatitis in 2 patients, and colitis requiring hospitalization in 2 patients. DISCUSSION: Despite the small number of cases, a high antitumor effect was observed with a CR rate of 21%. Although proteinuria and hypothyroidism were observed relatively frequently as adverse events, they were easily controlled and did not pose a major clinical problem.

We studied the clinicopathological findings of 5 patients with perforated colorectal cancer. Three patients were male, and the primary cancer site was left side colon in 4 patents. Two patients had endoscopy-related perforation. The chief complaint was abdominal pain in all cases. All patients underwent emergency surgery. Two patients had Stage â ¡ cancer, 3 had Stage â £. The mean ICU stay was 2.8 days. The average postoperative hospital stay was 71.8 days. Three patients were discharged home and 2 were transferred to other hospitals. The 3 patients who were discharged home received chemotherapy. Perforation of the cancer site is a risk factor for recurrence, and early recovery and additional treatment should be considered.

BACKGROUND: The number of patients taking antiplatelet therapy is increasing. However, there is no definitive guideline for the perioperative management of antiplatelet therapy. Conventionally, the discontinuation of antiplatelet drugs has been the basic treatment as perioperative management. Therefore, we investigated the risk of discontinuing aspirin concerning thrombotic complications in laparoscopic colorectal cancer surgery. METHODS: Between January 2015 and December 2019, a total of 729 patients underwent laparoscopic colorectal cancer surgery in Toyonaka Municipal Hospital. Sixty-four patients taking antithrombotic drugs aside from aspirin were excluded from this study; the remaining 665 patients were considered eligible and divided into three groups. The patients not taking aspirin were classified as the "Control group" (n = 588). Among the patients taking aspirin, those who continued preoperative aspirin were classified as the "Aspirin group" (n = 30), and those who discontinued preoperative aspirin were classified as the "No-aspirin group" (n = 47). The Aspirin, No-aspirin, and Control groups were compared retrospectively. RESULT: Among the 3 groups, there were no significant difference in operative time (p = 0.14), bleeding volume (p = 0.63), or postoperative hospital stay (p = 0.06). Assessing the postoperative complication, bleeding complications were significantly more frequent in the Aspirin group (p < 0.01), although those complications were all Clavien-Dindo grade II. In contrast, thrombotic complications were significantly more frequent in the No-aspirin group (p < 0.01). Note that those complications were all Clavien-Dindo Grade III/IV. This result suggested that discontinuing aspirin increased the risk of severe thrombotic complication. CONCLUSION: Discontinuation of aspirin as perioperative management in laparoscopic colorectal cancer surgery increased the risk of severe thrombotic complications.

The patient was a 78-year-old man. After 4 courses of GEM plus nab-PTX therapy for multiple recurrent liver metastases after pancreatic body cancer surgery, the patient was aware of general malaise and edema of the extremities. Blood tests showed pancytopenia, and he was admitted to the hospital with a diagnosis of chemotherapy-induced pancytopenia. On the second day, hemolytic anemia with crushed red blood cells was observed, suggesting thrombotic microangiopathy (TMA). Considering the possibility of thrombotic thrombocytopenic purpura(TTP), the patient was started on plasma exchange with steroids. After 7 days of plasma exchange, his thrombocytopenia, hemolytic anemia, and renal dysfunction improved, and he was discharged from the hospital on the 28th day. Although GEM-induced TMA is a life-threatening complication, there is no established treatment for it. We report a case of GEM-induced TMA that was successfully treated with plasma exchange.

A 60s male, who had laparoscopic ileocecal resection for ascending colon cancer 2 years ago, had enhanced computed tomography(CT)for follow-up and a 12-mm nodule in Douglas' pouch adjacent to right seminal vesicle and rectum was found. 18F-fluorodeoxyglucose(FDG)-positron emission tomography CT revealed abnormal accumulation of 18F-FDG only to the lesion(standardized uptake value max 2.60)and the diagnosis of peritoneal recurrence of ascending colon cancer was made. We planned and safely performed laparoscopic concomitant right seminal vesiculectomy in low anterior resection. The pathological diagnosis was peritoneal dissemination of colon cancer and the margin was pathologically negative. The postoperative course was smooth except for temporary dysuria and he was discharged on postoperative day 17. As of writing 1 year after surgery, the patient continues to do well with no sign of recurrence. Laparoscopic concomitant seminal vesiculectomy in low anterior resection can be a good option for the curative resection of peritoneal recurrence.

Disseminated intravascular coagulation(DIC)has a poor prognosis in gastric cancer. The patient was a 78-year-old man. He had been diagnosed with Stage â £ gastric cancer. Before chemotherapy, thrombocytopenia and elevated D-dimer occurred, and we diagnosed DIC. We started SOX therapy to treat gastric cancer with DIC. DIC improved on the 10th day after the onset of DIC. But developed DIC again on the 21st day. We started SOX therapy again. However, the DIC did not improve. The patient died 32 days after the initial DIC. Oxaliplatin regimen may be a potential treatment for DIC.

The patient was a 60's man, whose chief complaints were melena and weight loss. He visited our hospital, and further evaluation revealed rectal cancer(Ra)invading the abdominal wall with multiple liver metastases. The clinical diagnosis was cT4b(abdominal wall)N2bM1a(H1), cStage â £. We performed a transverse colostomy on the day prior to chemotherapy administration. He was administered 8 courses of FOLFOXIRI plus bevacizumab. After the chemotherapy, the primary tumor and liver metastases showed PR, with a diagnosis of ycT3N1bM1a(H1), Stage â £. We performed a robot-assisted laparoscopic low anterior resection for the primary tumor. Two months later, the partial resection of liver S6 and S8 was performed. The patient has been cancer-free for 6 months now.

A 60s-year-old male, who had laparoscopic partial colectomy with resection of left colic artery for descending colon cancer 8 years ago and completed 5-year-follow-up without the evidence of recurrence, was diagnosed as anastomotic recurrence of descending colon cancer, and referred to our hospital. We planned and safely performed single-incision laparoscopic colectomy(SILC)with intracorporeal anastomosis(ICA)(operation time of 390 min and estimated blood loss of 60 g). Following the adhesiolysis, the intracorporeal resection of the lesion was performed with automatic stapling device preserving middle colic and inferior mesenteric arteries and veins. Then, after the recovery of the specimen, ICA was performed as follows; after making a small hole just below the staple line at the opposite side of mesenteric attachment, the oral and the anal stump of colon was pulled-up and placed side-by-side with temporary strings and automatic suturing device was inserted into the holes and fired to form a side-to-side anastomosis, then the common stab incision was pulled- up with 3 temporary strings and closed with a stapler. The postoperative course was smooth and discharged on postoperative day 8. The ICA can be a good option for SILC when colonic and vascular tension would be the limiting factor of anastomosis.

PURPOSE: Pancreatic fistula (PF) is a common and serious complications after pancreaticoduodenectomy (PD). However, few studies have discussed the time required for PF healing in patients with this complication. This study investigates the PF healing time (PF-HT) and its association with findings of postoperative fistulography performed via the drainage tubes. METHODS: The subjects of this study were 35 patients with PF among a total of 144 patients who underwent PD for periampullary diseases in our hospital. PF-HT, which was defined as the duration from the first postoperative fistulography to removal of the drainage tubes, was assessed in the enrolled patients. Fistulography findings were classified into four types based on fluid collection and communication with the jejunal loop. We investigated the factors affecting the PF-HT, including the fistulography findings. RESULTS: The average PF-HT was 22 ± 20 days. Multivariate analysis revealed that the fistulography type was the only independent factor that affected PF-HT significantly. The PF-HT was significantly shorter in patients without fluid collection than in those with fluid collection. Moreover, those patients with fluid collection and a communication had a significantly shorter PF-HT than those without a communication. CONCLUSIONS: We found that fistulography findings were significantly associated with the PF-HT. This suggests that fistulography findings could help to predict the time needed for PF healing.

PURPOSE: Anatomical variation of the cystic duct (CD) is rare but can result in misunderstanding of the CD anatomy during laparoscopic cholecystectomy, potentially leading to bile duct injury. Therefore, the precise preoperative identification of CD variation is important. However, preoperative imaging analyses of the biliary system are not always possible or sufficient. We therefore investigated CD variations based on the anatomy of the hepatic vasculature. METHODS: This study enrolled 480 patients who underwent imaging before hepatobiliary pancreatic surgery. We assessed the variation of the CD and hepatic vasculature and evaluated the correlations among these variations. RESULTS: A variant CD anatomy was identified in 12 cases (2.5%) as CD draining into the right hepatic bile duct (BD) in 4 cases and into the right posterior BD in 8 cases. CD variation was significantly more common in cases with portal vein (PV) and BD variation than in those without the variation. We developed a scoring system based on the presence of PV and BD variations that showed good discriminatory power for identification of CD variants. CONCLUSION: Cases with a variant CD anatomy were more likely to exhibit variant PV and BD anatomies than cases with a normal CD anatomy. These findings will be useful for the preoperative identification of CD variants.

BACKGROUND: In pelvic surgery, it is important to anticipate potential anatomic variations, which may be unknown, and inter-relationships among intrapelvic vessels. Here, we comprehensively analyzed intrapelvic vessel patterns. METHOD: This retrospective analysis included 81 patients that underwent colorectal surgery in our institution in 2016. A total of 162 half-pelvises were imaged with contrast-enhanced computed tomography. We scrutinized thin-slice images. RESULTS: We found variations in the number of internal iliac veins. In 47.5% of cases, one internal iliac vein drained into the ipsilateral common iliac vein in both halves of the pelvis. In the other cases, several internal iliac veins were observed in one or both halves of the pelvis. We analyzed the inter-relationships between the superior gluteal artery and the sacral nerve plexus in pelvic halves. Superior gluteal arteries ran between the 5th lumbar nerve and 1st sacral nerves, in 82% of halves, and lateral to the 5th lumbar nerve, in 17% of halves. Dorsally, the superior gluteal artery ran on the medial side of the internal iliac vein in 15% of halves. In 28% of half-pelvises, two superior gluteal veins were observed. Superior gluteal veins passed through the sacral nerve plexus lateral to 5th lumbar, between 5th lumbar and 1st sacral, and between 1st and 2nd sacral nerve, in 42.0, 47.5, and 37.7% of halves, respectively. We evaluated the rate of symmetric pelvic anatomies, and found that all anatomic variations formed symmetrically, except the number of internal iliac veins. CONCLUSION: This study clarified the anatomical variations of intrapelvic vessels and their inter-relationships. These findings will benefit our understanding of pelvic anatomy and enhance the safety of radical surgery for treating pelvic diseases.

CASE: A 77-year-old woman was referred to our hospital for detailed examination of a cystic liver tumor. Contrast-enhanced CT and MRIshowed a cystic liver tumor with an enhanced mural nodule in S6 of the liver. Under a preoperative diagnosis of hemorrhagic hepatic cyst and mucinous cystic neoplasm(MCN)of the liver, extended posterior segmentectomy was performed. Histological examination of the tumor revealed no neoplastic cells, and the tumor was finally diagnosed as a hemorrhagic hepatic cyst of the liver. CONCLUSION: Similar to previous reports of hemorrhagic hepatic cysts, preoperative differential diagnosis from MCN of the liver was difficult in this case. Hemorrhagic hepatic cysts are rare and are sometimes confused with MCN of the liver, especially when an enhanced mural nodule is found in the cyst. The possibility of hemorrhagic hepatic cysts should be considered during diagnosis of liver cystic tumors.

A 70-year-old woman underwent treatment for cecal cancer(pT4bN1M0, Stage â ¢b)in 2010. Four years and 2 months after the first surgery, she underwent ileum resection for stenosis due to perineal dissemination(P3). Two years after this recurrence, during which time she had completed 26 courses of FOLFIRI plus bevacizumab(Bmab), 9 courses of capecitabine plus oxaliplatin(CapeOX)plus Bmab, and 3 courses of Cape, no peritoneal dissemination was detected by computed tomography( CT). Thereafter, an additional 19 courses of Cape plus Bmab were introduced, but CEA continued to increase. Right ovarian metastasis was suspected based on CT and FDG-PET/CT examination. Four years and 1 month after the initial recurrence of perineal dissemination, the patient underwent bilateral ovarian resection, during which the lack of peritoneal dissemination was confirmed. Pathologically, right ovarian metastasis was diagnosed. The patient is still alive 4 years and 6 months after the first operation.
