A case of gastric endocrine cell carcinoma with liver metastases treated with S-1/CDDP

Gastric endocrine cell carcinoma is known to be highly malignant with a poor prognosis, and no standard treatment has been established. We experienced a case of gastric endocrine cell carcinoma with liver and lymph node metastases. The lesions became resectable after chemotherapy with S-1/cisplatin (CDDP). The patient was a 68-year-old male. He had gastrointestinal endoscopy for screening without complains. The endoscopy findings showed that a type 3 gastric cancer on lesser curvature of ventricular angle of the stomach, and was histologically diagnosed as an endocrine cell carcinoma by the biopsy specimen. A computed tomography (CT) scan showed metastatic lesions at S2 and S3 of the liver, and No.6 lymph node enlargement. Thus he was diagnosed as gastric endocrine cell carcinoma with liver and lymph node metastases. He was treated chemotherapy with S-1/CDDP every 5 weeks. After these courses of treatment, liver and lymph node metastatic lesions had reduced in size, but the primary lesion was still remained. Then he suffered from a drug induced eruption due to S-1. We changed the chemotherapy to biweekly CPT-11/CDDP. After 21 courses, he underwent distal gastrectomy with lymph node dissection and a partial liver resection. Histological findings revealed that there were no cancer cells in removed specimens. He had treated 8 courses of CPT-11/CDDP therapy after the surgery, and survived for 5 years without recurrence.     

Complete recovery obtained with combined S-1 + CDDP therapy in a patient with multiple lung metastases from esophageal cancer

PURPOSE: There are numerous reports on the subject of effectiveness in radio-chemotherapy with regard to esophageal cancer, suggesting especially the combination therapy of 5-FU + CDDP aimed for recovery. Treatment becomes difficult when distal metastases appear during an adjuvant therapy followed by surgery. Our report here is a case in which a complete recovery was obtained after changing to S-1, a prodrug of 5-FU, in response to multiple lung metastases which appeared during the combined 5-FU + CDDP therapy followed by surgery for esophageal cancer. CASE: The patient was a 71-year-old male. Endoscopy during a physical examination showed a Type 1 tumor 27-30 cm from the anterior teeth. Detailed tests provided a preoperative diagnosis of esophageal cancer: Ut Type 1, T2-T3, N2, MO, IMO. A right thoracolaparotomic subtotal esophagectomy and retrosternal reconstruction were performed. Pathological findings showed well-differentiated squamous cell carcinoma, pT1b (sm), pN1 (106-rec R), pStage II. Postoperative combination of 5-FU + CDDP (day 1-5, 5-FU 500 mg; CDDP 10 mg/body) was started. Because of the appearance of multiple lung metastases after the completion of 3 courses, 2 courses of S-1 + CDDP (S-1 120 mg/body day 1-14; CDDP 5 mg/body day 1-5, day 8-12) were performed. After completing the chemotherapy, CT revealed the resolution of the lung metastases and complete recovery was diagnosed. Following this, a treatment with S-1 alone was continued until the appearance of bone metastases at which time radiotherapy was performed. The treatment is currently ongoing and no recurrence of the lung metastases has been shown. CONCLUSION: There have been numerous reports of the combination of S-1 + CDDP in esophageal cancer for NAC or in inoperable cases. However, our report suggests that this method may be effective in cases of recurrence or distal metastases.     

A case of complete response to S-1 plus CDDP in early-stage mucosal esophageal cancer

We report a case of early-stage mucosal esophageal cancer, showing a complete response to S-1 and cis-diamminedichloplatinum (CDDP). The patient was a 67-year-old man with synchronous double primary early-stage mucosal esophageal and advanced gastric cancer. We planned neoadjuvant chemotherapy with S-1 and CDDP for the advanced gastric cancer and endoscopic mucosal resection for the early-stage esophageal cancer. After the first course of chemotherapy, the endoscopy revealed that the esophageal cancer had become a normal mucosal lesion, and the biopsy was negative for cancer. We diagnosed a complete response to S-1 and CDDP in early-stage esophageal cancer. After two courses of chemotherapy, distal gastrectomy was performed. The patient is still alive with no sign of recurrence at 16 months after the disappearance of the original tumor. These results suggest that chemotherapy with S-1 plus CDDP may be effective in early-stage esophageal cancer.     

A successful resected case of advanced esophageal cancer with early gastric cancer responding to neoadjuvant chemotherapy of docetaxel, CDDP and 5-FU

A 72-year-old male with a chief complaint of dysphagia was admitted to our hospital. Upper gastrointestinal endoscopic examination showed double cancers with thoracic esophageal cancer in the middle esophagus and gastric cancer in the antrum. Pathological examinations of the double cancer revealed the first one to be moderately-differentiated squamous cell carcinoma and the second to be well-differentiated adenocarcinoma. Computed tomography (CT) of the chest and abdomen showed no distant or lymph node metastases. Clinical stagings of the double cancer were stage II (T2N0M0)in esophageal cancer and stage I A (T1N0M0) in gastric cancer. The patient received neoadjuvant chemotherapy using docetaxel, CDDP and 5-FU. After 2 courses of chemotherapy, the adverse event was grade 2 in leucopenia and grade 2 in alopecia. Repeated macroscopic and histological examinations after chemotherapy revealed that the esophageal cancer had significant reductions in the size of tumors, leading to a partial response, and the gastric cancer had disappeared, leading to a complete response. He underwent thoracoscopy-assisted esophagectomy in the prone position, and laparoscopy-assisted gastric tube reconstruction. This neoadjuvant chemotherapy of docetaxel, CDDP and 5-FU might be effective and tolerable as with patients with double cancer of esophageal and gastric cancers.

Pathological complete response in an elderly patient with locally advanced gastric cancer treated with S-1/CDDP

We report a patient with locally advanced gastric carcinoma successfully treated with S-1/CDDP. The patient was a 77-year-old woman who had gastric cancer surgically diagnosed as T4N2, invading the pancreas and mesocolon. After the firsts exploratory laparotomy, chemotherapy was begun as follows. S-1(80 mg/day)was orally administered for 3 weeks followed by 2 weeks' rest as a course, and CDDP(75 mg/body)was administered by intravenous drip on day 8. Because of severe anorexia and nausea, however, the CDDP administration had to be discontinued. Therefore, we changed the procedure to S-1 single treatments, 2 weeks' administration followed by 2 weeks' rest. The total 9 courses of this procedure proved successful. Subsequently, she underwent curative surgery consisting of total gastrectomy with D2 lymph node dissection, combined with distal pancreatectomy and splenectomy, and obtained pathological CR. S-1/CDDP appears to be an effective treatment modality for advanced gastric cancer.     

A successful case with CPT-11 + CDDP chemotherapy for recurrent gastric cancer of the remnant stomach

We report a successful case with irinotecan (CPT-11 60 mg/m2) + cisplatin (CDDP 30 mg/m2) chemotherapy (once in 2 weeks) for recurrent gastric cancer of the remnant stomach. A 77-year-old man was performed a distal gastrectomy for duodenal ulcer 42 years ago. He had a total gastrectomy for gastric cancer of remnant stomach when he was at 73 years old. After the surgery, we treated this patient with S-1 mono-therapy for five courses. However, we finished this treatment for lymph-node metastases. Next we treated him with CPT-11 + CDDP. An abdominal CT revealed a CR after 6 courses. We finished this treatment after 12 courses for anemia (grade 3). After the treatment, the metastatic lymph-nodes appeared in no change. So we considered that CR was continued for 3.5 years.     

Pathological complete response in advanced gastric carcinoma by S-1/CDDP combination chemotherapy

A59 -year-old woman was referred to our hospital for a close examination and treatment of an advanced gastric carcinoma. A physical examination and CT scan showed that the right cervical and axillar lymph nodes were swelling, and a histopathological examination of the axillar lymph node revealed metastatic growth of the gastric carcinoma (Stage IV). Then, we started S-1/CDDP combination chemotherapy. S-1 (80 mg/m2/day)was orally administered for 3 weeks followed by 2 weeks of rest, and CDDP (60 mg/m2) was administered by drip on day 8. Since the distant metastases were greatly reduced after 6 courses of combination therapy, a distal gastrectomy with lymph nodes dissection (D2) was performed. Histopathological examination of the resected tissues revealed no residual cancer cells, suggesting a pathologically complete response. The clinical course after the operation went well without any complications, and the patient is alive with no evidence of recurrence 1 year after surgery. S-1/CDDP combination chemotherapy appears to be one of the effective treatments for advanced gastric carcinoma.     

A patient with esophageal cancer recurrence responding to S-1 combined with cisplatin (CDDP)

We administered a combination chemotherapy of S-1 plus cisplatin (CDDP) therapy to a patient with recurrenced cancer of esophagus in lymph node. S-1 (80 mg/m(2)/day), taken out of the capsule, was administered via the catheter for tube feeding on day 1 to day 21 and CDDP at 60 mg/m(2)/day by intravenous drip infusion on day 8 for 3 weeks followed by a drug-free 2 week period as the first course. After 2 courses, CT findings showed a complete regression of the lymph node for complete response (CR). He has been alive for 10 months without recurrence. Combined use of S-1 and CDDP is effective as chemotherapy for recurrenced esophageal cancer.     

Pedunculated gastric tube interposition in an esophageal cancer patient with prepyloric adenocarcinoma

Gastric carcinoma is one of the malignancies that are most frequently associated with esophageal carcinoma.We describe herein our device for advanced esophageal cancer associated with early gastric cancer in the antrum.A 57-year-old man presenting with dysphagia and upper abdominal pain was admitted to our hospital.Preoperative examinations revealed locally advanced squamous cell carcinoma (SCC) of the middle thoracic esophagus (T3N0M0 Stage ⅡA) and mucosal signetring cell carcinoma of the gastric antrum (T1N0M0 Stage ⅠA).Although the gastric tumor appeared to be an intramucosal carcinoma,its margin was obscure,so endoscopic en-bloc resection was considered inadequate.We chose surgical resection of the gastric tumor as well as the esophageal SCC after neoadjuvant chemotherapy with 5-fluorouracil and cisplatin for advanced esophageal cancer.Following transthoracic esophagectomy with three-field lymph node dissection,the gastric carcinoma was removed by gastric antrectomy,which preserved the right gastroepiploic vessels,and a pedunculated short gastric tube was used as the esophageal substitute.Twenty-eight months after the surgery,the patient is well with no evidence of cancer recurrence.Because it minimizes surgical stress and organ sacrifice,gastric tube interposition is a potentially useful technique for esophageal cancer associated with localized early gastric cancer.     

Two cases of stage IV gastric cancer undergoing adjuvant surgery after down staging by chemotherapy

CASE 1: A 72-year-old man with epigastralgia was diagnosed with gastric cancer and referred to our hospital. An abdominal CT scan revealed liver metastasis and para-aortic lymph node metastasis. He was treated with S-1+CDDP. After 4 courses of this treatment, the liver metastasis and para-aortic lymph node metastasis disappeared, and adjuvant surgery was performed. There has been no recurrence for 16 months postoperatively. CASE 2: A 66-year-old man with anorexia was diagnosed with gastric cancer and referred to our hospital. An abdominal CT scan revealed para-aortic lymph node metastasis. He was treated with S-1+CDDP. After 9 courses of this treatment, para-aortic lymph node metastasis disappeared, and adjuvant surgery was performed. Eight months after the operation, lymph node metastases were confirmed by abdominal CT scan, and he was treated with chemotherapy as an outpatient as of 13 months after the operation. We experienced two cases of Stage IV gastric cancer undergoing adjuvant surgery after down staging by chemotherapy. It was suggested that adjuvant surgery to highly advanced gastric cancer could improve the prognosis of patients.     

A case of unresectable advanced gastric cancer treated with S-1/low-dose CDDP combination chemotherapy through jejunostomy

A 70-year-old woman with unresectable advanced gastric cancer accompanied by peritoneal dissemination underwent jejunostomy, and was treated with S-1 and low-dose CDDP. One course consisted of S-1 (80 mg/day) via an intestinal fistula tube from days 1 to 14. This was followed by 7 days rest, and CDDP (20 mg/day) was administered by 1-hour continuous intravenous infusion on day 1 and 8. She continued to receive this chemotherapy for a total of 14 courses, followed by 3 courses of a weekly paclitaxel regimen. She died 14 months after surgery. All chemotherapy had been conducted in an outpatient setting. We concluded that the administration of S-1, combined with low-dose CDDP (div) through a jejunostomy, can improve the quality of life (QOL) of a patient who has unresectable advanced gastric and is incapable of oral intake. We report this rare case with a review of the literature.     

Two cases of advanced gastric cancer, successfully treated with TS-1/CDDP combination chemotherapy--case report

We reported 2 cases with advanced gastric cancer, successfully treated with TS-1 and CDDP. Case 1 had Type 3 gastric cancer with left supra-clavicular (Virchow) and para-aortic lymph node metastases. Those distant node metastases completely disappeared after two courses of neoadjuvant chemotherapy (NAC) consisting of TS-1/ CDDP, and radical surgery for cure was conducted. The second case had Type 3 carcinoma with peritoneal dissemination. The primary lesion significantly decreased after four courses of the combination chemotherapy. The patient has been alive for 1 year and a half after 14 courses of TS-1/CDDP with stable disease. Significance of TS-1/CDDP in far advanced gastric cancer was discussed.     

A case report of long-term survival of endocrine cell carcinoma of the esophagus with chemo-radiation therapy

The patient was an 84-year-old man, who was diagnosed with cT3N2 (101L, 109L) M0, stage III esophageal cancer. The tumor, immunohistochemically, was stained positive for CD56 and NSE yielding a definitive diagnosis of endocrine cell carcinoma of the esophagus. We selected chemo-radiation therapy (5-FU/CDDP and 2 Gy/day total 60 Gy) for this patient. As adjuvant chemotherapy, 7 courses of chemotherapy with 5-FU/CDDP, was performed. At 8 months from the chemo-radiation therapy, the disease was diagnosed as cCR. But two years later, lung metastasis appeared, so we started chemotherapy with docetaxel/CDDP/5-FU. After 2 courses, lung metastasis was almost disappeared. He has been survived for four years and five months after chemo-radiation. This case suggests that chemo( FP) -radiation therapy and adjuvant chemotherapy could be an effective treatment for endocrine cell carcinoma of the esophagus.     

Three successful cases with CPT-11 + CDDP chemotherapy where S-1 failed to respond to recurrent gastric cancer

We report three successful cases with irinotecan (CPT-11 60 mg/m2) + cisplatin (CDDP 30mg/m2) chemotherapy (once in 2 weeks) where S-1 failed to respond to recurrent gastric cancer. Case 1: A total gastrectomy and splenectomy were performed for a cardiac gastric cancer (T3, N2, H0, P0, CY0, por 1, Stage IIIB). An abdominal CT revealed paraortic lymph node metastases 4 months after the surgery. No reductions were noted after S-1 monotherapy. We next treated this patient with CPT-11 + CDDP. An abdominal CT revealed a CRin after 11 courses. Case 2: A total gastrectomy, splenectomy and cholecystectomy were performed for a cardiac gastric cancer (T3, N3, H0, P0, CY1, tub1, Stage IV). After the surgery, we treated this patient with S-1 mono-therapy. However, we finished this treatment for abdominal recurrence. We next treated this patient with CPT-11 + CDDP. An abdominal CT revealed a CR after 24 courses. Case 3: A distal gastrectomy and cholecystectomy were performed for a pyloric gastric cancer (T2, N1, H0, P0, CY0, tub 2, Stage II). An abdominal CT revealed paraortic lymph node metastases 10 months after the surgery. We treated this patient with S-1 + paclitaxel (PTX) chemotherapy. No reductions were noted after 2 courses. We next treated this patient with CPT-11 + CDDP. An abdominal CT revealed a CR after 8 courses.     

A case of elderly advanced squamous cell lung carcinoma successfully treated with nedaplatin and S-1 combination chemotherapy

A 7 4-year-old male was referred to our hospital for an abnormal chest shadow pointed out by a medical examination. A chest computed tomography revealed a tumor shadow 39 X 32mm in size in his left upper lobe in January, 2010. Pathological examination of biopsy specimens showed squamous cell carcinoma of the lung. Although there was no distant metastasis, multiple metastases to mediastinal lymph nodes was noted. He was diagnosed as Stage III A(cT2aN2M0). Considering his age and the histology of the disease, systemic chemotherapy with nedaplatin and S-1 was performed. The diameter of the primary lesion was decreased from 39mm to 18mm after 4 courses of chemotherapy, and was considered as partial response (PR)according to the RECIST criteria. The adverse events were grade 2 appetite loss, grade 3 neutropenia, and grade 2 thrombocytopenia. Recently, various new agents for treating non-squamous cell lung carcinoma have been developed, but there has been little progress in the treatment of squamous cell lung carcinoma. We experienced a patient with advanced squamous cell lung carcinoma who responded with CDGP/S-1 combination chemotherapy. We are now conducting a phase I / II clinical study to verify the usefulness of this regimen against advanced squamous cell lung carcinoma.     

A long-surviving patient with unresectable advanced gastric cancer treated with S-1 and biweekly paclitaxel combination chemotherapy as second-line treatment

A 59-year-old man with type 3 gastric cancer(signet-ring cell carcinoma)underwent simple laparotomy because of peritoneal dissemination.S -1/CDDP was started.Since the icterus of Grade 2 had appeared after 2 courses, S-1 and biweekly paclitaxel combination chemotherapy was started as second-line treatment.Throughout treatment, there was no adverse event, and this regimen was continued for 14 courses(25 months).He died 32 months after his first visit.S -1/PTX may play an important role as second-line chemotherapy for patients with unresectable advanced gastric carcinoma.     

S-1 chemotherapy for cancer of the gastric tube used for esophageal reconstruction following surgery for esophageal cancer

We used S-1 chemotherapy to treat 5 patients with cancer of the gastric tube used for esophageal reconstruction through the posterior mediastinal route following surgery for esophageal cancer. The response rate was 40%, the median survival 15 months, and 3 patients still survive. In those 3 patients, the gastric tube cancer was at a resectable stage, but the patients elected to have chemotherapy instead. One patient has survived 21 months after responding completely to 2 cycles of combined chemotherapy with S-1 and cisplatin. Another has survived 15 months after partially respondingto S-1 chemotherapy. And the third has survived 46 months after endoscopic treatment, radiation therapy and S-1 chemotherapy. S-1 chemotherapy thus appears to be an effective treatment for cancer of the gastric tube after surgery for esophageal cancer.     

A case of gastric cancer presenting with obstructive jaundice and responding to biweekly CPT-11 and CDDP combination administration

A 74-year-old man was suffering from Borrmann type 2 advanced gastric cancer with abdominal lymph node metastases and multiple lung metastases. He started to undergo outpatient treatment with oral administration of TS-1. But pyloric stenosis was found after 6 courses of TS-1 chemotherapy, so he underwent palliative distal gastrectomy. TS-1 chemotherapy was continued afterwards, however obstructive jaundice was found. So combination chemotherapy of CPT-11 60 mg/m(2)and CDDP 30 mg/m(2)biweekly was selected as a second-line therapy after PTCD. As no side effects were found, he could be treated on an outpatient basis by CPT-11 60 mg/body and CDDP 30 mg/body biweekly. Four months has passed since the palliative operation, and the PTCD tube was successfully removed. The abdominal lymph nodes had decreased in size and the patient has maintained good QOL. Thus, combination CPT-11 and CDDP therapy could well be a new candidate for a second-line chemotherapy in outpatients.     

A case of advanced gastric cancer found to be remaining by gastrectomy after a clinically complete response to chemotherapy

The patient was a 72-year-old woman diagnosed with advanced gastric cancer, hepatic portal lymph node and para-aortic lymph node metastases. After five courses of S-1/CDDP combination therapy, both the primary tumor and lymph node metastases disappeared clinically. She wished to continue chemotherapy instead of having a resection. After three more courses of S-1/CDDP therapy, gastric cancer and lymph node metastases were still completely regressed, but complications of carcinoma of the gallbladder were suspected. Gastrectomy was performed with cholecystectomy, and a histopathological examination revealed cancer cells remaining in the gastric submucosa and xanthogranulomatous cholecystitis. We consider surgical therapy for clinically completely disappearing advanced gastric cancer by chemotherapy, in addition to case report.
