RESUMEN

We assessed the therapeutic effect of curative resection in patients with multiple relapses of colorectal cancer using the time to surgical failure(TSF)as an index. We included 24 patients who experienced recurrence after curative resection of primary colorectal cancer at our department between 1993 and 2015. Curative resection for multiple relapses was possible in these patients. The sites of recurrence included the liver, lungs, peritoneum, lymph nodes, localized, and brain in 9, 8, 3, 3, 2, and 1 patients, respectively. The relapse occurred in 2 organs in 2 patients. The TSF after curative resection of recurrent lesions was 25.6 months, with a 5-year TSF-free rate of 40.2%. The clinicopathological factors associated with poor prognosis were age B65 years at the time of recurrence, absence of distal metastasis at primary onset, and only 2 curative resections for relapses. However, there was no difference in prognosis because of the number of twice recurrent lesions. Therefore, curative resection should be proactively performed as long as feasible in colorectal cancer patients with multiple lesions or multiple relapses.

RESUMEN

We report a rare case ofrectal neuroendocrine carcinoma(NEC)following sigmoidectomy of sigmoid colon cancer. NEC of the rectum is a rare disease. It has an extremely poor prognosis and a high potential for malignancy with hematogenous and lymph node metastases. A 90-year-old man who had carcinoma ofthe sigmoid colon 2 years ago was found to have rectal NEC based on endoscopy findings. He underwent the Hartmann operation. Histological and immunohistochemical analyses showed NEC. Four months after the surgery, he developed local recurrence with lymph node metastasis. He was not administered chemotherapy because ofhis old age. Although the patient needed strict outpatient care, he remained symptom-free 4 months after the Hartmann operation.

RESUMEN

The efficacy of laparoscopic surgery for elderly patients aged over 80 years who have colorectal cancer was investigated concerning complications. Sixty-five patients over 80 years old who underwent colorectal cancer resection until January 2018 were enrolled. Factors that led to complication were analyzed retrospectively. Thirty-three men and 32 women were included, with a median age of 83 years. Forty-eight cases were located at the colon; and 17, at the rectum. The median operating time was 164 minutes, including 39 cases treated with the laparoscopic approach. Postoperative complications were observed in 28 cases(43.1%), of which 15(23.1%)had a Clavien-Dindo(CD)classification of Grade BⅡ. These cases had significantly prolonged postoperative hospital stay. Complications included 10 cases of incisional surgical site infection(SSI), 9 cases of ileus, 6 cases of melena, 2 cases of urinary infection, 2 cases of urinary disorder, and 1 case of postoperative death. Open surgery was the only significant factor associated with the incidence of CD classification of BⅡ(p=0.0330). Among the complications, the incisional SSI was reduced by laparoscopic surgery(p=0.0050). The number of laparoscopic surgeries reduced the incidence of CD classification BⅡ of complications in elderly patients aged over 80 years who had with colorectal cancer resection. The use of incisional SSI also decreased with the use of laparoscopic surgery. Laparoscopic surgery for colorectal cancer in elderly patients may lead to reduced complication rates.

RESUMEN

To evaluate the less invasiveness of laparoscopic surgery for colorectal cancer, we compared open and laparoscopic surgery for sigmoid or recto-sigmoid cancer operations undergoing the same procedures. One hundred forty-three patients curatively resected with D3 dissection were enrolled. All cases underwent the following procedure; high ligation of the inferior mesenteric artery(IMA)with median approach and double stapling technique(DST)for anastomosis. The clinicopathological factors were examined in 70 cases of open surgery(OC)and 73 cases of laparoscopic surgery(LAC). The mean age of all cases was 66(38-88)years, including 83 men and 60 women. The mean operation time was 189(82-413)minutes and the mean blood loss was 45(5-1,025)mL. Postoperative complications were reported in 45 cases including 10 cases with surgical site infection(SSI)and 10 cases with remote infection(RI). There was no difference in sex, BMI, PS, and ASA between the 2 groups; however, the patients were significantly older and the tumor maximum diameter significantly larger in the OC group. There was no significant difference in operation time but the blood loss was significantly lower in the LAC group. There were no differences in postoperative complications, first gait, WBC, and body temperature on postoperative day(POD)3, but the first flatus was earlier and the CRP level was significantly lower on POD 3 in the LAC group. There was no difference in the CRP level on POD 3 in the age, tumor diameter, and blood loss which showed a difference in the both group. Laparoscopic surgery was considered less invasive than open surgery because the serum CRP level was lower in the LAC group.

RESUMEN

The case was a 76-year-old man. He visited our hospital for a positive fecal occult blood test finding at a medical examination. A colonoscopy revealed a macroscopic, 30 mm, type-1 lesion in the cecum. We performed laparoscope-assisted ileocolic resection and D3 dissection, with a diagnosis of cecum cancer. In postoperative histopathological examination, the tumor in the cecum was diagnosed as a well-differentiated tubular adenocarcinoma. In addition, a low-grade appendiceal mucinous neoplasm(LAMN)was observed on the distal side of the appendix. The patient has survived for 9 months after surgery without recurrence. We report this case with a review of the literature.

RESUMEN

We herein report a case of lung metastases from rectal cancer treated with FOLFIRI plus ramucirumab(Ram)therapy after salvage for a long time. A 44-year-old woman underwent low anterior resection for rectal cancer. Fifteen months after the surgery, mFOLFOX6 plus bevacizumab(BV)therapy was initiated for left obturator lymph node metastases. Although the target lesion shrunk, left lung metastasis was found 36 months after the surgery. Partial resection of the lung metastasis was performed, and carbon-ion radiotherapy for pelvic recurrence was administered. Following these treatments, mFOLFOX6 plus BV therapy was administered again for multiple lung metastases 42 months after the surgery. FOLFIRI plus BV therapy, TAS- 102 plus BV therapy, and regorafenib were then administered because of the disease progression. Although the best supportive care was provided after disease progression, FOLFIRI plus Ram therapy was initiated owing to the patient's wish. Although Grade 3 hematological toxicity was observed, severe digestive symptoms were not noted. Long-term administration(approximately 1 year, 21 courses)of the drugs was possible with withdrawal. The patient died due to disease progression 66 months after recurrence. We experienced a case in which FOLFIRI plus Ram therapy after salvage line could be administered for a quite long time. It has been suggested that anti-VEGF drugs with different targets may improve the prognosis even as a late line of therapy if it is tolerable.

RESUMEN

To clarify the prognostic impact of postoperative inflammatory status, serum CRP levels on POD3 after radical resection (POD3 CRP)were evaluated as an indicator of inflammatory response after surgery in patients with colorectal cancer. Of the colorectal cancer patients who underwent radical resection at our department between 2000 and 2015, 916 patients with Stage Ⅰto Ⅳdisease were included in the analyses. The patients were divided into 2 groups according to high and low POD3 CRP levels. The POD3 CRP levels of the patients were analyzed for the 75th percentile that was 12.16mg/dL(range, 0.06- 33.78). The cancer-specific 5-year survival rate was 80.6%in patients in the high group and 90.5%in those in the low group, indicating poor prognosis in patients with high values. POD3 CRP levels were an independent prognostic factor in the multivariate analysis. It was suggested that the degree of inflammation after surgery influences the postoperative prognosis after radical resection for colorectal cancer.

RESUMEN

A 60-year-old woman was admitted for abdominal distention, abdominal pain, and anorexia. Abdominal CT showed a 30×20 cm mass with contrast effect. gastrointestinal stromal tumor(GIST) of the omentum or the mesenterium was suspected. Peritoneal nodules were also recognized. We performed palliative surgery. The tumor was considered to have originatedfrom the greater omentum andinvolvedthe marginal artery of the transverse colon. We performedpartial excision of the transverse colon andresection of the tumor. Immunohistochemically, the tumor cells were c-kit(+), CD34(+), S100(-), andDOG1(-), with 1 fission image for 50 fields of view with high magnification. The patient was diagnosed with high-risk GIST originating from the greater omentum. The patient was started on imatinib administration on the 37th day but died on the 109th day.

RESUMEN

This study was conducted to evaluate the prognostic factors in patients with unresectable Stage Ⅳ colorectal cancer. One hundred and twenty-five patients who underwent either primary resection or chemotherapy for unresectable Stage Ⅳ colorectal cancer and were treated at our hospital between April 2004 and March 2014 were enrolled this study. In multiple univariate analysis, the overall survival(OS)was significantly longer in the palliative resection and chemotherapy groups. Upon dividing the 125 patients in 3 groups(the intensive chemotherapy group[L-OHP or CPT-11 regimen], extensive chemotherapy group[other regimen], and non-chemotherapy group), the intensive chemotherapy group showed significantly longer OS. Next, upon comparing the patients based on the treatment they received(surgery plus chemotherapy, surgery alone, and chemotherapy alone), the surgery plus chemotherapy group showed longer OS. With both studies combined as 5 groups, only the surgery plus intensive chemotherapy group showed longer OS. This is shown in unresectable Stage Ⅳ cancer patients, wherein resection of the primary lesion in addition to intensive chemotherapy contributes to longer OS.

RESUMEN

We report a case of ascending colon cancer with hepatic metastases that was treated by CapeOX plus bevacizumab with remarkable efficacy. A 40-year-old female patient presented with a medical history of surgery for resection of right breast cancer4 years ago, left-sided transverse colon 2 years ago, and right ovarian cancer 6 months ago. Follow-up computed tomography(CT)found wall thickening from the ascending colon to cecum. She was diagnosed with an ascending colon cancer by colonoscopy, and underwent right hemicolectomy. One month after the surgery, her serum marker carcinoembryonic antigen(CEA)and carbohydrate antigen 19-9(CA19-9)levels were high. She was diagnosed with unresectable multiple hepatic metastases by CT 2 months after the surgery. Her tumor was epidermal growth factor receptor(EGFR)- positive and wild-type for RAS; she received 4 courses of CapeOX plus bevacizumab. Thereafter, liver metastases were remarkably decreased in size, and she could undergo central bisegmentectomy. Pathology examination revealed no tumor and that the center of the tumor was changed to necrotic tissue and the surrounding area was changed to fibrous tissue and lymphocyte infiltration. The patient is disease-free since the last operation.

RESUMEN

PURPOSE: We analyzed to clarify an outcome of multiple resections of metastases from colorectal cancer. PATIENTS AND METHOD: Total 7 cases who underwent several resections for metastases from colorectal cancer in Saiseikai Kurihashi Hospital after 2010 were enrolled for analysis. RESULT: Age of patients at the time of the primary site resection was 67(45-78)year-old, including 4males and 3 females. Patients located at cecum/ascending/sigmoid/rectosigmoid/upper rectum were 1/1/2/2/1 respectively. Metachronous metastases were found in 5 patients. There were 1 patient for Stage I , 2 patients for Stage III a and III b each and all Stage III patients received adjuvant chemotherapy. The resected organs were 9 in lung, 8 in liver, 1 case in lymph node, local site and peritoneum and the median resected sites were 3(2-4)lesions. In 17 months median observation periods after latest resection, 5 cases have not been prolapsed including 3 cases with chemotherapy. Two cases were relapsed with unresectble status. One case died for 24 months and one case is under the chemotherapy for 12 months. Five year survival rate was 75% and 2 year prolapse free rate was 66.7%, since the relatively good prognosis was obtained by multiple resections. CONCLUSION: The cases that multiple resections with R0 were able to perform for the metastases were analyzed. Although cases which become finally to be unresectable exist, it is suggested that the relatively good prognosis might be obtained by multiple resections for metastases.

RESUMEN

The aim of this study was to clarify prognosis for curative resection performed for cases of colorectal cancer with synchronous liver metastasis and to use the findings as future treatment indices. Subjects comprised 61 patients who underwent curative resection at our hospital for colorectal cancer accompanied by synchronous liver metastasis between 1996 and 2014. The degree of liver metastasis was H1 for 47 cases and H2 for 14 cases. The Grade of liver metastasis was A for 29 cases, B for 18 cases, and C for 14 cases. Liver resection was performed simultaneously with that of the primary lesion for 33 cases, and after that of the primary lesion for 28 cases. The post-curative resection survival period was 58.0 months, and the 5-year survival rate was 49.9%. In terms of the relationship between prognosis and clinicopathological factors, prognosis was found to be poor when the wall depth of the primary lesion was pT4 and when the liver metastasis Grade was B or C. Meanwhile, prognosis did not differ depending on the timing of liver metastasis resection, whether chemotherapy was performed after liver resection, and whether curative resection was performed for initial occurrence only or recurrence resection was performed. The results indicated that for cases of colorectal cancer with synchronous liver metastasis, primary lesion wall depth and liver metastasis Grade were prognostic factors, and that the treatment strategy did not necessarily have to consider resection timing.

RESUMEN

We report a case of effective treatment comprising mFOLFOX6 plus bevacizumab for neuroendocrine carcinoma of the ascending colon. A 60-year-old woman was admitted for diarrhea and abdominal pain. Colonoscopy showed a Type 2 tumor in the ascending colon. She was diagnosed with neuroendocrine cell carcinoma based on biopsy and immunostaining. CT and MRI showed liver metastasis and lymph node #12a metastasis. Right hemi-colectomy, lymphadenectomy, and partial hepatectomy were performed(T4a, N2, M1b, Stage IV). Neuroendocrine cell carcinoma(small-cell type)was finally diagnosed based on a histological examination because the nuclear fission image was 30(/10HPF)and the Ki-67 index was 42%. Three months after the surgery, multiple lymph node metastases were found using CT and MRI. mFOLFOX6 plus bevacizumab was initiated. After 4 courses of the chemotherapy, the metastases responded completely. A total of 10 courses of chemotherapy were administered. About 2 years and 6 months after the surgery, no recurrence is allowed.

RESUMEN

INTRODUCTION: There are few reports on the outcome of relapsed cases after curative resection for colorectal cancer(CRC) with adjuvant oxaliplatin-based chemotherapy. Thus, we analyzed such cases. PATIENTS AND METHOD: In total, 48 patients with CRC who received oxaliplatin-based postoperative adjuvant chemotherapy from 2012 were analyzed. The clinical course was examined in 9 cases ofrecurrence. RESULTS: Stages II, III a, and III b(1, 3, and 5 cases, respectively)were judged as recurrence in 9 cases. Metastatic sites were the lungs, local sites, liver, and peritoneum(3, 3, 3, and 1 case[s], respectively). The median time to relapse was 390 days. There were 2 cases ofwild -type RAS and 7 cases ofmutant RAS. Although R0 resection was performed in 1 case, re-relapse was recognized. Another 8 cases involved induced chemotherapy. An oxaliplatin-based regimen was administered as first-line treatment in 4 of8 cases. At present, 5 patients died, and 3 of8 cases could not progress to second-line treatment. The overall survival(OS)after relapse was 475 days, and survival more than 3 years was not observed. CONCLUSION: Recurrent cases after Cur A resection for CRC with oxaliplatin-based adjuvant chemotherapy were examined. Although the 3-year RFS and 5-year OS were relatively good, the prognosis after relapse was quite poor.

RESUMEN

We herein report a Stage IV case ofrectal cancer in a patient who achieved stable disease and was treated monthly with fluorouracil(FU)monotherapy plus bevacizumab(Bmab)against relapse after residual tumor resection and withdrawal because ofref usal to continue chemotherapy, even though a marked response was obtained with standard chemotherapy. A 73-year-old woman visited a former hospital in 2014, and was diagnosed with rectal cancer with liver and lung metastases (diagnosed with Rb, T3, M1b[liver, lung]cStage IV). Chemotherapy(mFOLFOX6 plus Bmab)was initiated with a consideration of conversion. After 5 courses, she moved to our hospital. Since she was not aggressive to chemotherapy from the beginning, an imaging examination was performed after 9 courses. The primary lesion and lung metastases had disappeared, and there was only one liver metastasis. Partial hepatic resection was performed to attempt chemotherapy withdrawal following informed consent. Six months after surgery with no therapy, since relapse in the rectum and lungs was confirmed, laparoscopic rectal amputation was performed to control the primary tumor. Chemotherapy containing FU monotherapy plus Bmab was reinitiated after 15 months of withdrawal because liver and lung metastases increased 5 months after rectal amputation. Two months after resuming chemotherapy, the metastatic lesion decreased in size, and the tumor marker level normalized. The same regimen is continued monthly, and the response has been maintained for 17 months(infusions of 5-FU/LV plus Bmab, 18 courses).

RESUMEN

The patient was 55-year-old woman, undergoing Hartmann operation by the sigmoid colon diverticulum perforation, 2 years later visited our hospital with abdominal pain. Although lower endoscopy and histological examination could not be performed due to stoma stenosis, we diagnosed cecal carcinoma, liver metastasis, distant lymph node metastasis from CT and PET-CT, CapeOX plus Bmabtherapy and IRIS plus Bmabtherapy were performed. After that, repeated intestinal obstruction due to exacerbated stoma stenosis, metastatic lesion increased in CT examination, furthermore the patient had hope of stoma closure, we decided to resect the primacy tumor, performed subtotal colonectomy and stoma closure. Pathological diagnosis revealed RAS wild type. After surgery, Pmabplus CPT-11 therapy was performed and the metastatic lesion was temporarily shrunk but re-exacerbated, the patient died 2 years 2 months after the first treatment started, 7 months after the primary tumor resection. In the treatment of colorectal cancer, when metastatic lesion is unresectable, chemotherapy is often carried out except when the primary tumor is symptomatic. In our case, although the primary tumor was asymptomatic, an intestinal obstruction due to stoma stenosis was developed and it was necessary to examine whether to use anti-EGFR antibody drugs, therefore we performed operation.

RESUMEN

The aim of this study was to clarify the prognosis of cases with recurrent colorectal cancer that underwent curative resection in order to determine index for recurrent colorectal cancer treatment. Of the cases that exhibited recurrence after undergoing curative resection for primary colorectal cancer at our hospital between 1993 and 2013, this study targeted the 109 cases for which curative resection was possible. The sites of recurrence were the liver(58 cases), the lungs(27 cases), the peritoneum (11 cases), local sites(9 cases), lymph nodes(8 cases), and the anastomotic sites(6 cases). Of these, 10 cases exhibited metastasis to 2 organs. The median survival time after metastasectomy was 75.3 months, and the 5-year survival rate was 53.8%. The primary lesion histological type being a poorly differentiated adenocarcinoma/mucinous carcinoma, degree of progression upon initial onset being Stage III b or greater, and disease-free interval being less than 2 years were associated with poorpr ognosis. Specifically, histological type and disease-free interval were found to be independent factors that correlated with prognosis. Meanwhile, no differences were observed for prognosis related to the number of recurrent organs, the number of recurrent nodules, or the number of times curative resection was performed after recurrence. While the histological type and disease-free interval determine prognosis in cases with recurrent colorectal cancer performed curative resection, it appears that if curative resection is possible, aggressive resection should be pursued even for cases of multiple or repeated recurrence.

RESUMEN

Here we report a case in which a locally advanced ascending colon cancer was successfully treated with anti-EGFR immunotherapy combined with chemotherapy and curative resection, and recurrent cancer was treated with the same chemotherapy. A 71-year-old man was diagnosed with ascending colon cancer in our department. No distant metastasis was observed, but curative resection was considered impossible because of extensive local cancer invasion. Because a genetic analysis revealed the presence of the wild-type KRAS gene, 6 courses of mFOLFOX6 plus cetuximab were administered. A cPR was obtained and curative resection was performed. The final diagnosis was ypT3N1M0, ypStage III a colon cancer, and chemotherapy improved the cancer stage to Grade 1b. Six courses of FOLFOX6 were then administered, followed by observation. After 2 years 6 months, a tumor of approximately 5 cm in size was noted in the right buttock using surveillance CT and was diagnosed as recurrent colon cancer. We considered further curative resection difficult and therefore 6 courses of mFOLFOX6 plus panitumumab were administered, a cPR was obtained, and right hip tumor extirpation surgery was performed. These results suggest that chemotherapy combined with anti-EGFR antibody immunotherapy is effective in treating recurrent colon cancer.

RESUMEN

We report a case of an advanced rectal cancer recurrence that responded completely to chemo-radiotherapy. The patient was an 80-year-old woman. Low anterior resection with D2(prxD3)lymph node dissection was performed. Sixteen months after operation, CEA level elevated but no recurrence foci were found in any image tests. Administration of TS-1 was initiated since recurrence was highly suspected. Twenty seven months after operation, PET-CT detected local recurrence in the posterior wall of the vagina. After construction colostomy, chemo-radiotherapy(60 Gy+oral UFT)was performed and CEA level dropped promptly to the normal value. No relapse was pointed out in CT scans or MRI tests. There were not any signs of recurrence through 112 months after chemo-radiotherapy.

RESUMEN

AIM: We examined the outcome of treatment with first-line chemotherapy with bevacizumab(Bmab)formetastatic colorectal cancer in our hospital to clarify the outcome for RAS mutant patients. SUBJECTS AND METHODS: From January 2013 to April 2016, 28 patients who initiated standard chemotherapy(2 chemotherapeutic agents)with Bmab as the first-line regimen for metastatic colorectal cancer were enrolled in this retrospective study. Time to treatment failure(TTF)and overall survival(OS)were analyzed. RESULTS: The median age was 66.5(46-81)years old, including 16 men and 12 women, 11 cases with RAS wild type, and 17 cases with mutant type. The response rate was 30.8% in 2 cases of CR, 6 cases of PR, 14 cases of SD, 4 cases of PD, and 4 cases with conversion surgery after chemotherapy. TTF was 6.5 months and OS was 32.1 months. Among those with RAS mutations, 3 cases received conversion surgery. TTF of the mutant and wild type were 6.3 and 5.6 months, respectively, and OS was 35.8 and 32.1 months, respectively, without any significant difference. In addition, excluding conversion cases, the OS of mutant and wild type patients was 22.7 and 29.5 months, respectively. CONCLUSION: The outcome of treatment using first-line chemotherapy with Bmab for metastatic colorectal cancer with RAS mutations was retrospectively analyzed. There was no difference in therapeutic effect between RAS mutated and not, and it seems that an OS of more than 20 months can be expected for those with RAS mutations with this choice of treatment.
