RESUMO
BACKGROUND: We previously reported the response rate of a phase II OGSG1602 study on panitumumab in chemotherapy-naive frail or elderly patients with RAS wild-type unresectable colorectal cancer (CRC) [Terazawa T, Kato T, Goto M, et al. Oncologist. 2021;26(1):17]. Herein, we report a survival analysis. METHODS: Patients aged ≥65 years and considered unsuitable for intensive chemotherapy or aged ≥76 years were enrolled. Primary tumors located from the cecum to the transverse colon were considered right-sided tumors (RSTs); those located from the splenic flexure to the rectum were considered left-sided tumors (LSTs). RESULTS: Among the 36 enrolled patients, 34 were included in the efficacy analysis, with 26 and 8 having LSTs and RSTs, respectively. The median progression-free survival (PFS) and overall survival (OS) were 6.0 [95% CI, 5.4-10.0] and 17.5 months (95% CI, 13.8-24.3), respectively. Although no significant differences existed in PFS between patients with LST and RST {6.6 (95% CI, 5.4-11.5) vs. 4.9 months [95% CI, 1.9-not available (NA), P = .120]}, there were significant differences in OS [19.3 (95% CI, 14.2-NA) vs.12.3 months (95% CI, 9.9-NA), P = .043]. CONCLUSION: Panitumumab showed favorable OS in frail or elderly patients with RAS wild-type CRC and no prior exposure to chemotherapy. Panitumumab may be optimal for patients with LSTs (UMIN Clinical Trials Registry Number UMIN000024528).

PURPOSE: In the 5th edition of the World Health Organization classification, appendiceal goblet cell adenocarcinoma (GCA) is categorized separately from neuroendocrine tumors and other appendiceal adenocarcinomas. We clarified the clinicopathological characteristics of Japanese appendiceal GCA. METHODS: We designed a retrospective multicenter cohort study and retrieved the data of patients with appendiceal neoplasms and histologically diagnosed appendiceal goblet cell carcinoid (GCC) treated from January 2000 to December 2017 in Japan. The available GCC slides were reviewed and diagnosed with a new grading system of GCA. RESULTS: A total of 922 patients from 43 institutions were enrolled; of these, 32 cases were patients with GCC (3.5%), and 20 cases were ultimately analyzed. The 5-year survival rate was 61.4% (95% confidence interval: 27.4-83.2), and the median survival time was 93.1 months. For peritoneal metastasis, regional lymph node metastasis was a significant factor (p = 0.04), and Grade 3 was a potential factor (p = 0.07). No peritoneal metastasis was observed in either T1/2 patients (n = 2) or Grade 1 patients (n = 4). We were unable to detect any significant factors associated with regional lymph node metastasis. CONCLUSION: For peritoneal metastasis, regional lymph node metastasis was a significant factor, and Grade 3 was a potential factor.

We present a case of oligo lymph node metastasis in a 70s man who had previously undergone subtotal gastrectomy for advanced gastric cancer in the prepylorus. Postoperatively, adjuvant chemotherapy was administered for a duration of 1 year. During the third postoperative year, elevated tumor markers and lymph node enlargement prompted a diagnosis of lymph node metastasis. Subsequent chemoradiotherapy resulted in a complete response(CR), which has been sustained for 2 years without any recurrence. The outcomes of this case indicate that chemoradiotherapy stands as a viable treatment option for oligo lymphatic recurrence in gastric cancer.

PURPOSE: Although early tumor shrinkage (ETS) is a predictor of improved overall survival (OS), the association between ETS and health-related quality of life (HRQOL) remains unclear for patients with metastatic colorectal cancer (mCRC) treated with first-line cetuximab plus chemotherapy. METHODS: The data were collected from a prospective trial that assessed HRQOL using the EORTC QLQ-C30. The impact of ETS on HRQOL was estimated using a linear mixed-effects model for repeated measures. RESULTS: ETS was achieved in 82 (64.1%) of 128 mCRC patients treated with first-line cetuximab plus chemotherapy, and these patients had a significantly longer OS than those without ETS (HR, 0.38; 95% CI, 0.20-0.72; P = .002). Asymptomatic patients with ETS had a favorable OS, while symptomatic patients without ETS had a worse OS (2-year OS rates, 77.8% vs. 42.5%). Symptomatic patients with ETS had similar outcomes as asymptomatic patients without ETS (2-year OS rates, 64.1% vs. 67.0%). For symptomatic patients, ETS was associated with improved HRQOL scores between baseline and 8 weeks: the mean changes for patients with and without ETS were 5.86 and -4.94 for global health status (GHS)/QOL, 26.73 and 3.79 for physical functioning, and 13.58 and -3.10 for social functioning, respectively. The improved HRQOL was comparable to that of asymptomatic patients without ETS. For asymptomatic patients, ETS showed a decreased deterioration in HRQOL. CONCLUSION: Our findings highlight the importance of ETS for HRQOL and prognostic estimates, and assessing ETS may provide clinically useful information for physicians and patients to make more informed decisions.

We report a case of recurrent descending colon cancer in which QOL was maintained for a long period by performing resection with intestinal reconstruction, chemotherapy, and radiotherapy for local recurrence with hydronephrosis. A man in his 60s with good ADL underwent laparoscopic left hemicolectomy for descending colon cancer. After 4.5 years postoperatively, computed tomography and positron emission tomography showed a local recurrence of 32 mm contacting with the left external iliac artery and sigmoid colon, and CAPOX plus BEV was started. When cholecystitis developed after 5 chemotherapy courses, the recurrent lesion was resected simultaneously. After 8 months, repeated recurrent lesion with a major axis of 13 mm with left hydronephrosis was observed at the same site. After 3 years of chemotherapy after placing the left ureteral stent, CEA level gradually increased, and tumor growth was observed. Because of the aggressive chemotherapy limitation due to high proteinuria, 66 Gy/22 Fr radiotherapy was performed. After 1 month of radiotherapy, the CEA level decreased and proteinuria improved in that period. Radiotherapy for local recurrence can be a useful interval for chemotherapy and effective local control.

An 83-year-old man presented with melena and weight loss. Upper gastrointestinal endoscopy showed type 3 advanced gastric cancer with pyloric stenosis. Surgical findings revealed numerous peritoneal dissemination, then gastro-jejunum anastomosis was performed. The oral diet was resumed on POD4, however severe dysphagia occurred immediately on POD6. There were no specific findings on MRI/MRA and nasal endoscopy. Serum antibodies related to neuromuscular diseases and connective tissue diseases were also negative. Despite the rehabilitation, the dysphagia remained. Before total parenteral nutrition on POD16, hypophosphatemia was discovered(1.4 mg/dL). His dysphagia disappeared with the improvement in the serum phosphate level. Hypophosphatemia might be caused by an inadequate intake as urine phosphate, serum calcium and serum PTH levels were normal. We present a recent case of severe dysphagia due to hypophosphatemia in a patient with peritoneal dissemination of gastric cancer.

LESSONS LEARNED: The 3-year disease-free survival rate of the twice-daily regimen was not inferior to that of the conventional three-times-daily regimen, and the twice-daily regimen did not lead to an increase in adverse events. The effectiveness of the twice-daily regimen highlights an increased number of treatment options for patients. This will facilitate personalized medicine, particularly for elderly or frail patients who may experience more severe side effects from the combination therapy. BACKGROUND: Tegafur-uracil (UFT)/leucovorin calcium (LV) is an adjuvant chemotherapy treatment for colorectal cancer. We conducted a multicenter randomized trial to assess the noninferiority of a twice-daily compared with a three-times-daily UFT/LV regimen for stage II/III colorectal cancer in an adjuvant setting. METHODS: Patients were randomly assigned to group A (three doses of UFT [300 mg/m2 per day]/LV [75 mg per day]) or B (two doses of UFT [300 mg/m2 per day]/LV [50 mg per day]). The primary endpoint was 3-year disease-free survival. RESULTS: In total, 386 patients were enrolled between July 28, 2011, and September 27, 2013. The 3-year disease-free survival rates of group A (n = 194) and B (n = 192) were 79.4% and 81.4% (95% confidence interval, 72.6-84.4-74.5-85.9), respectively. The most common grade 3/4 adverse events in group A and B were diarrhea (3.9% vs. 7.3%), neutropenia (2.9% vs. 1.6%), increase in aspartate aminotransferase (4.0% vs. 3.9%), increase in alanine aminotransferase (6.2% vs. 6.8%), nausea (1.7% vs. 3.4%), and fatigue (1.1% vs. 2.3%). CONCLUSION: Group B outcomes were not inferior to group A outcomes, and adverse events did not increase.

LESSONS LEARNED: Panitumumab monotherapy showed favorable efficacy and feasibility in the treatment of frail or elderly patients with RAS wild-type unresectable colorectal cancer. It is especially effective for left-sided tumors; therefore, panitumumab as first-line treatment could be an additional therapeutic option for frail elderly patients, particularly in those who are unsuitable for upfront oxaliplatin-based or irinotecan-based combination regimens. BACKGROUND: First-line panitumumab monotherapy is expected to be well tolerated and improve survival in patients ineligible for intensive chemotherapy. However, its safety and efficacy in chemotherapy-naïve frail or elderly patients with unresectable RAS wild-type (WT) colorectal cancer (CRC) have not been studied. The aim of this phase II trial was to evaluate the efficacy and safety of panitumumab as first-line treatment. METHODS: We conducted a multicenter phase II study on patients aged ≥76 years or ≥65 years considered unsuitable for intensive chemotherapy. Panitumumab 6 mg/kg of intravenous infusion was administered every 2 weeks. The primary endpoint was disease control rate (DCR). Secondary endpoints included progression-free survival (PFS), overall survival (OS), response rate (RR), time to treatment failure (TTF), and incidence of grade 3 or 4 toxicities. RESULTS: Thirty-six patients (median age: 81 [range, 67-88] years) were enrolled between February 2017 and August 2018. Two patients were excluded from the analysis of efficacy: one from lack of image examination at baseline and the other from lack of a measurable lesion. Thirty-three (91.6%) patients had a performance status (PS) of 0 or 1, whereas two (5.6%) patients and one (2.8%) patient had a PS of 2 and 3, respectively. Twenty-eight patients (77.8%) had left-sided CRC, whereas eight (22.2%) had right-sided CRC. The RR was 50.0% (95% confidence interval [CI], 32.4-67.6), including three patients (8.8%) who had complete responses. A total of 26.5% had stable diseases, resulting in a DCR of 76.5% (90% CI, 61.5-87.7). The RR of patients with left- and right-sided tumors was 65.4% (95% CI, 44.3-82.8) and 0.0% (95% CI, 0.0-36.9), respectively. Major grade 3 or 4 nonhematologic toxicities were rash (n = 6, 16.7%), hypomagnesemia (n = 4, 11.1%), fatigue (n = 3, 8.3%), paronychia (n = 2, 5.6%), and hyponatremia (n = 2, 5.6%). The only grade 3 hematologic toxicity was neutropenia (n = 1, 2.8%). CONCLUSION: Panitumumab monotherapy showed favorable efficacy and feasibility in frail or elderly patients with RAS WT unresectable CRC. Survival analysis including OS, PFS, and TTF is currently in progress.

Spontaneous bacterial peritonitis is defined as an ascitic fluid infection without an evident intra-abdominal surgically treatable source. The diagnosis is established by a positive ascitic fluid bacterial culture and an ascitic fluid absolute polymorphonuclear leukocyte(PMN)count≥250 cells/µL. Here we report the case of 81-year-old female patient who was diagnosed with spontaneous bacterial peritonitis after gastrectomy for gastric cancer. The laparoscopic distal gastrectomy and D1+ lymph node dissection were performed for Stage â gastric cancer, and the postoperative course was uneventful. The patient presented with abdominal pain and was hospitalized again on the third day from the discharge. Computed tomography showed an accumulation of ascites, and the ascitic fluid polymorphonuclear leukocyte count was 9,973 cells/µL. The patient was diagnosed with spontaneous bacterial peritonitis, and antibacterial agent was performed. Abdominal pain and accumulation of ascites had been improved, and the ascitic fluid polymorphonuclear leukocyte count had decreased clearly. The patient discharged on the 57th day from the operation. Spontaneous bacterial peritonitis after gastrectomy for gastric cancer was rare. We report this rare case, along with a discussion of the literature.

Portal vein thrombosis after laparoscopic colorectal cancer surgery is rare and sometimes lethal. We report a case of asymptomatic portal vein thrombosis found during postoperative adjuvant chemotherapy(CAPOX)after laparoscopic surgery for rectal cancer. A male patient in his 60s underwent postoperative adjuvant chemotherapy( CAPOX). The elevation of liver enzyme before the chemotherapy was moderate enough to start. The liver enzyme was increased mildly during the chemotherapy. Computed tomography 27 weeks after the operation revealed the thrombus from the main portal vein to the right branch and posterior branch, and atrophy of the lateral segment with narrowed left branch. Blood flow was confirmed to be maintained by ultrasonic Doppler. We decided to discontinue the chemotherapy and started anticoagulant therapy with Warfarin. Thrombosis was disappeared 2 weeks later, and liver function went back to normal range after 8 weeks. Liver dysfunction during chemotherapy should be noted not only for drug-induced liver damage, but also for the possibility of postoperative asymptomatic portal vein thrombosis.

A 77âyearâold man came to our hospital with complaints of abdominal pain and difficulty to defecate. Abdominal CT scan showed an abnormal region in the ascending colon, which was suspected to be an ascending colon cancer. Dâdimer was remarkably high, and the platelet count was 63,000/µL; these results suggested disseminated intravascular coagulation caused by tumor activation. After he was admitted, we performed a contrast enhanced CT, and found no signs of remote metastasis. We decided to resect the tumor without colonoscopy examination in order to release the DIC state. After the surgery, the platelet count did not increase, and leukopenia was observed. We conducted a bone marrow biopsy, and made a diagnosis of disseminated carcinomatosis from colon cancer. The patient's condition did not improve, and he died on day 42 after admission. Pathological autopsy was performed and several minimal remote metastases were found throughout the body.

A woman in the 60s. She was referred to our hospital because the fecal occult blood test was positive. Colonoscopy was performed. Cancer is found in the transverse colon. There were no metastases in the lungs and liver. Laparoscopic left hemicolectomy was performed. Histopathological examination was adenocarcinoma(tub1>tub2>muc), pT1b, pN2, ly2, v1, pPM0, pDM0, pRM0, budding(0, Grade 1), fStage â ¢b. After postoperative adjuvant chemotherapy, she visited an outpatient clinic 8 months after surgery with a complaint of swelling of both inguinal lymph nodes. The swollen inguinal lymph node was relatively soft and there was no evidence of infection. A biopsy of the bilateral lymph nodes was performed. Histopathological examination revealed adenocarcinoma containing mucus components. These findings were consistent with histological findings in transverse colon cancer. Based on these results, we diagnosed metastatic recurrence from transverse colon cancer to both inguinal lymph nodes.

A 58-year-old woman underwent surgery and systemic chemotherapy(FOLFIRI plus panitumumab)for ascending colon cancer with multiple lymph node and liver metastases; the preoperative Virchow lymph node aspiration cytology showed adenocarcinoma.After 4 courses of chemotherapy, contrast-enhanced CT showed an embolus in the left subclavian vein.An anticoagulation therapy was started, but the embolus tended to increase.Three months later, the patient developed dyspnea and was diagnosed with pulmonary artery thromboembolism and superior vena cava thrombosis.Transcatheter examination was performed because of the anticoagulation-resistant embolism, and the biopsy revealed tumor embolism due to colon cancer.She died of respiratory failure 10 days after the biopsy.The tumor directly infiltrating the vein because of left subclavian lymph node metastases might have resulted from increased tumor emboli.Although cases of tumor emboli infiltrating the veins and developing from lymph node metastases are rare, a transcatheter biopsy may help to detect them.

Here we report a case of a 41-year-old male patient who underwent resection of a desmoid tumor originating from the greater omentum with no history of open surgery. An elastic hard mass was palpated in the left upper abdomen, but there were no abnormalities on serum chemical tests, including tumor markers. Computed tomography showed a parenchymal tumor located near the descending colon. Integrated positron-emission tomography and computed tomography revealed moderate accumulation of tracer in the tumor. An intra-abdominal malignant mesenchymoma was suspected and surgery was performed. The tumor was located in the anterior portion of the greater omentum. It partially invaded the diaphragm, and the affected regions were concurrently resected. The resected specimen measured 80 mm at longest diameter. The cut surface was grayish white and parenchymal. The histopathological findings showed the atypical spindle shaped tumor cells grown with collagen fiber progression. Immunohistochemical staining for ß-catenin showed strong staining in the nuclei and cytoplasm of tumor cells. The patient was diagnosed with desmoid tumor originating from the greater omentum. The desmoid tumor with no history of open surgery was rare. We report this rare case, along with a discussion of the literature.

A 78-year-old woman had a semicircular ulcerative lesion of AV 7 cm, as detected using colonoscopy, and pathologic examination based on a biopsy showed well-differentiated adenocarcinoma. On contrast-enhanced CT of the liver, a number of nodular lesions that seemed to be liver metastases were observed. It was decided to administer chemotherapy containing mFOLFOX6 plus panitumumab. Bilateral hemorrhage of the ocular conjunctiva and eyelid edema were observed from the 4th day of chemotherapy. Edema of the lips, epidermolysis, and erythema appeared in addition to vision impairment. We diagnosed her with SJS based on these symptoms. We also administered steroid pulse therapy. Eyelid edema improved, and vision impairment improved 24 hours after the initiation of treatment. For severe cases with visual impairment, systemic administration of corticosteroids is recommended. In this case, administering steroid pulse therapy from an early stage resulted in improvement without sequelae.

We report a case of multiple lung metastases of RAS mutant type descending colon cancer with development of nephrotic syndrome after the introduction of FOLFIRI plus ramucirumab(RAM). A female patient in her 50s underwent adjuvant chemotherapy with capecitabine and oxaliplatin after primary tumor and partial lung resection. For recurrent multiple lung metastases, 4 years of capecitabine and bevacizumab therapy was administered. FOLFIRI plus RAM therapy was introduced because of tumor progression. After treatment, the patient showed increased urine protein content, decreased serum albumin levels, marked hypertension, and increased edema, and was diagnosed with nephrotic syndrome. The patient's condition improved with prednisolone, additional doses of antihypertensive, and diuretics. Even in cases where it is possible to control proteinuria during bevacizumab administration, it is necessary to keep in mind that RAM administration as second-line therapy may cause nephrotic syndrome.

A 75-year-old woman presented with the chief complaint of right lower abdominal pain. There was mild tenderness in the lower right abdomen and a mass was palpated. There were no peritoneal irritation symptoms. A CT examination was performed. The ascending colon was invaginated with a part of the cecum and ileum. Wall thickening was observed in the advanced part. Colon cancer was suspected. The preoperative diagnosis was considered to be an intussusception with cecal cancer at the advanced part. A laparoscopic ileocecal resection was performed. The intraoperative findings were as follows. The tumor was invading the ascending colon, but it was possible to restore it by pressing on the developed part with forceps. The pathological diagnosis was Type 2, muc>tub1, pT4aN0M0, pStageâ ¡b. The postoperative course was good. Water intake was started on the next day, meals were started from the second day, and the patient was discharged on the 9th day after the operation. Cecal cancer complicated with intussusception is a relatively rare disease. We report a case that was laparoscopically operable.

An 80-year-old woman who received on anticoagulant therapy for atrial fibrillation was diagnosed with ER-negative HER2-positive breast cancer(cT4bcN1M0, Stage â ¢B). She underwent mastectomy with skin graft and lymphadenectomy, but was evaluated to be too old for standard chemotherapy and HER2-directed therapy. Four months after the operation, she was diagnosed with regional lymph node metastasis and underwent radiotherapy. Moreover, 9 months later, other recurrent sites were revealed in the parasternal lymph node and thoracic wall without distant metastasis. Radiotherapy could be performed around these secondary recurrent sites while avoiding overlap. After 2 years, solitary contralateral axillary lymph node metastasis was diagnosed by PET-CT. She underwent Lt axillary lymphadenectomy. The intrinsic breast cancer subtype did not change. Patient performance status was kept to achieve a good quality of daily life. Eight months later, she diagnosed with primary pancreatic cancer and received 13 cycles of chemotherapy until her death from pancreatic cancer 14 months later. During chemotherapy, no recurrence of breast cancer was observed.

We observed a case of a large collection of mediastinal and retroperitoneal emphysema, which developed after a transanal local excision for an early lower rectal carcinoma and was treated conservatively. An 80's female patient presented with a chief complaint of bowel difficulty, which was diagnosed as mucosal prolapse syndrome with anal sphincter dysfunction. Endoscopic colonoscopy showed full circumferential proliferation of the mucosal membrane including a semicircular protruding lesion, on the upper side of the dentate line. Biopsy revealed findings indicative of an adenocarcinoma(tub1/pap), Group 4. After a sufficient informed consent was taken, a transanal local excision under spinal anesthesia was conducted discontinuously over half of the circumference. The patient underwent partial-thickness excision, partially full-thickness, and the defects are closed as much as possible. A fever of 38 degrees Celsius was recognized on the 1st postoperative day, and a CT scan, on the 2nd postoperative day, showed a large collection of retroperitoneal and mediastinal emphysema tracking upwards to the nasopharynx. Since fever was the only subjective symptom present, antibiotic therapy under fasting was chosen. The mediastinal emphysema had mostly resolved by the 10th postoperative day. Even though standard transanal excision is not a treatment under air supply there is a risk leading mediastinal and retroperitoneal emphysema.

A 39-year-old woman with very sever obesity was admitted to our hospital for a right breast redness and hardness. Her height, weight and BMI were 166 cm, 145 kg and 52.6 kg/m2. Her breast had peau d'orange. CT scan showed swelling of whole right breast and Level I , II lymph node. We performed core needle biopsy and diagnosed as the inflammatory breast cancer with ER and HER2 positive. We introduced chemotherapy(pertuzumab, trastuzumab and paclitaxel)and nutrition counseling in order to reduce her body weight. After 4 courses of chemotherapy, the clinical complete response was obtained and her body weight decreased to 125 kg. We performed mastectomy and axillary node resection and confirmed pathological complete response. Adjuvant chemotherapy(5-FU, epirubicin and cyclophosphamide), adjuvant trastuzumab therapy, postmastectomy radiation therapy and adjuvant hormonal therapy were administered. There have been no signs of recurrence as of 2 years after the operation.
