The purpose of postoperative adjuvant chemotherapy is to achieve a higher or rate of surgical radical cure and to eliminate recurrence of cancer. There are many differences between colon cancer and rectal cancer. Recurrence of colon cancer almost always metastasizes to liver and lung Adjuvant chemotherapy is indicated for stage III and high risk stage II. Standard adjuvant chemotherapy is a combination of Leucovorin and 5-FU, or a combination of oxaliplatin, 5-FU and Leucovorin. Combination treatment with VEGF antibody and EGFR antibody has shown no evidence of effectiveness in adjuvant chemotherapy. In rectal cancer, radiation is the standard form of neoadjuvant therapy. In the future, treatment of colorectal cancer may make remarkable improvement with the introduction of new drugs.

The patient is a 62-year-old female who underwent a right hemicolectomy for type-2 ascending colon cancer (moderately-differentiated adenocarcinoma, ss, n0, H0, P0, M0, stage II). Six months after the surgery, a solitary metastatic focus was expressed in the liver S3. Because schizophrenia was present concurrently, tegafur and uracil/folinate (UFT/Leucovorin) treatment was selected and performed for 3 months. Because the tumor shrank afterward, a partial hepatectomy was performed to obtain a curative resection. In a pathological examination of the resected focus, cicatricial/necrotic findings were observed, but no cancer cells were observed; hence, it was determined to be a pathological complete response (CR). In regard to chemotherapy for distant metastasis of colorectal cancer, many molecular-targeted agents are being introduced, thus resulting in more treatment options; however, depending on the patient's background, UFT/LV treatment can be an effective treatment option.

As an adjuvant treatment for Dukes B2 and C colon cancer, adding oxaliplatin (L-OHP) to a regimen of fluorouracil and Leucovorin improved disease-free survival in Western countries. In Japan, however, adjuvant chemotherapy with L-OHP is not commonly used to treat Stage III colon cancer. We report the present condition of adjuvant treatment for colon cancer in our hospital. Between September 2009 and December 2011, 66 patients with Stage III colon cancer were enrolled after curative surgery. The details of adjuvant therapy with fluoropyrimidines with and without L-OHP were explained to the patients. After the explanation, 33.3% of the patients(IIIa: 18.9%, IIIb: 55.5%) selected L-OHP chemotherapy. Regardless of the side effects, adjuvant chemotherapy including L-OHP is expected to protect against cancer recurrence in patients with Stage IIIb colon cancer.

We report a rare case of a 78-year-old woman with metachronous axillary lymph node metastasis originating from descending colon cancer. Her past medical history included right mastectomy for breast cancer at age 53 and distal gastrectomy for gastric cancer at age 70. She underwent a left hemicolectomy for descending colon adenocarcinoma in April 2011. Four months after that operation, 3 enlarging nodules in the left lung and a swollen left axillary lymph node were detected by computed tomography. No tumor was detected in the left breast by ultrasonography and mammography. The lung tumors were resected thoracoscopically, and the left axillary lymph node was excised. These specimens were histologically diagnosed as moderately differentiated adenocarcinoma, which had metastasized from colon cancer, not from the previous breast or gastric cancer. She received adjuvant chemotherapy with uracil and tegafur (UFT) plus Leucovorin for 6 months and is still alive after 12 months without recurrence.

We report a case of advanced relapsed colon cancer, which had multiple liver and spleen metastasis, controlled for about two years by capecitabine therapy. A 60-year-old female had been diagnosed with ileus due to sigmoid colon cancer in August, 2005. She received sigmoidectomy and adjuvant chemotherapy (Leucovorin/5-fluorouracil therapy). In postoperative observation, multiple liver and spleen metastasis were detected by computed tomography in February, 2008. Therefore, she was administered twenty courses of FOLFOX therapy. However, a peripheral nerve disturbance appeared. There fore chemotherapy was changed from FOLFOX therapy to FOLFIRI therapy. After 2 courses of FOLFIRI therapy, she had severe nausea, vomiting, appetite loss and diarrhea. Therefore, chemotherapy was changed from FOLFIRI therapy to capecitabine therapy. After capecitabine therapy, her multiple liver and spleen metastasis disappeared, and complete response has continued for about 2 years. She has remained on capecitabine therapy and has a good quality of life.

The patient was a 54-year-old man who had undergone resection of the sigmoid colon for unresectable sigmoid colon cancer with multiple liver( H1), lymph node, and lung metastases at the previous hospital. Chemotherapy with 5-fuorouracil, Leucovorin, and oxaliplatin (mFOLFOX6) plus bevacizumab was initiated after surgery. The outcome was partial response. The patient was introduced to our hospital because he had relocated. Based on the findings of the patient's computed tomography( CT) and positron emission tomography( PET)-CT scans, we decided to perform radical resection. We performed partial hepatectomy( S7 and S8) and pancreatoduodenectomy for metastases to the hepatoduodenal ligament lymph node. After confirming that there was no recurrence, he underwent right partial pneumonectomy. Currently, the patient shows no signs of recurrence. The therapy for colon cancer should include aggressive radical surgery to control metastasis.

A 61-year-old man underwent sigmoidectomy with partial cystectomy for advanced sigmoid colon cancer with unresectable multiple liver metastases at the Okayama University Hospital in June 2006. Pathological examination revealed moderately differentiated adenocarcinoma, pStage IV( pSI[ bladder], pN0, pH2, pP0, pM0), as per the Japanese Classification of Colorectal Carcinoma, seventh edition. The patient underwent systematic chemotherapy with irinotecan, 5-fluorouraci( l 5-FU), and folinic acid( FOLFIRI) and oxaliplatin, Leucovorin, and 5-FU( mFOLFOX6) for 13 months. In July 2007, hepatectomy was performed as the liver metastatic lesions had shrunk to a resectable size. Follow-up computed tomography (CT) in November 2009 revealed recurrence in the liver and lung. Subsequently, lateral segmentectomy was performed for the recurrent liver lesions, and radiofrequency ablation( RFA) was performed for the lung lesions. After having undergone RFA, the patient is doing well without any re-recurrence. We encountered a patient with advanced sigmoid colon cancer who was successfully treated with multimodality therapy. For patients with advanced or recurrent colorectal cancers, curative resection can lead to a good prognosis; however, in most patients, it is difficult to achieve curative resection by upfront surgery. Multimodality therapy could facilitate curative resection, thereby resulting in a good prognosis.

A 65-year-old woman was referred to our hospital for examination of anemia. Colonoscopy showed a type 1 tumor in the ascending colon with nearly complete stenosis that was diagnosed as a tubular adenocarcinoma. Computed tomography (CT) revealed swelling of the regional, periaortic, and celiac lymph nodes and lymphangitis carcinomatosa. The patient was diagnosed as having Stage IV ascending colon cancer, and neoadjuvant chemotherapy was administered to avoid non-curative resection. The patient was treated with cetuximab and oxaliplatin, Leucovorin, and 5-fluorouracil( mFOLFOX6) combination chemotherapy. After 6 courses of chemotherapy, the primary lesion and multiple lymph node swellings greatly reduced in size and lymphangitis carcinomatosa improved. Accordingly, right colectomy with D3 nodal dissection was performed. The patient was recurrence free at her 8-month follow-up examination. Neoadjuvant chemotherapy with molecular targeted drugs is useful in the treatment of patients with unresectable primary cancer.

A 62-year-old man presented to a hospital with left buttock pain, and sacral neoplasia was suspected. He was referred to our hospital. Colonoscopy( CS) and bone biopsy showed rectal cancer with metastasis to the sacrum. There was no bleeding or ileus associated with the primary lesion, and the sacral metastasis was unresectable; therefore, we decided to provide palliative care for pain relief. Radiation therapy( 40 Gy) was performed on the sacral metastasis and included the primary lesion, and zoledronate was administered concomitantly. Both CS and computed tomography (CT) showed tumor regression of both the primary and metastatic lesions, and the patient's carcinomatous pain was alleviated. Irinotecan, 5- fluorouracil, and Leucovorin (FOLFIRI)+cetuximab was administered to reduce the progression of the primary lesion. After 3 months, CT showed significant tumor regression of both the primary and metastatic lesions. The sacral metastasis was no longer evident on the CT images, and positron emission tomography( PET)-CT did not show fluorodeoxyglucose (FDG) accumulation. The primary lesion had shrunk and become flat, but biopsy indicated residual lesion. Although clinically the frequency of bone metastasis of colon cancer has been reported to be 8.6 to 10.7%, single metastasis is not often seen. In this report, we present a case of advanced rectal cancer with bone metastasis, which was successfully treated with chemo-radiation therapy.

We report a case of a 60-year-old woman with abdominal distension who was treated with self-expandable metal stent (SEMS) placement in the proximal transverse colon. She was found to have severe bowel obstruction due to advanced transverse colon cancer on plain computed tomography (CT) and colonoscopy. We performed colonic stenting safely, and the symptom promptly improved. Defecation and flatus were observed on the same day of stenting, and the patient was able to start drinking and eating on the next day. Enhanced abdominal CT revealed multiple liver metastasis, peritoneal dissemination, ascites, and cystic ovarian tumor. After treatment with 1 course of 5-fluorouracil, Leucovorin, and oxaliplatin (mFOLFOX6), the patient was discharged on day 14 after admission. The rapidly enlarging ovarian tumors and primary colonic lesion with SEMS were surgically removed after treatment with mFOLFOX6 for 4 months in an outpatient basis. The patient has been alive with a good quality of life (QOL) and being treated with bevacizumab plus mFOLFOX6/Leucovorin, 5-fluorouracil, and irinotecan( FOLFIRI) for 6 months. SEMS placement could be safe and effective for the treatment of obstruction of the right colon, and could maintain a good QOL in patients.
