Paclitaxel and capecitabine, which have distinct mechanisms of action and toxicity profiles, have each shown high activity as single agents in gastric cancer. Synergistic interaction between these two drugs was suggested by taxane-induced upregulation of thymidine phosphorylase. We, therefore, evaluated the antitumour activity and toxicities of paclitaxel and capecitabine as first-line therapy in patients with advanced gastric cancer (AGC). Patients with histologically confirmed unresectable or metastatic AGC were treated with capecitabine 825 mg m(-2) p.o. twice daily on days 1-14 and paclitaxel 175 mg m(-2) i.v. on day 1 every 3 weeks until disease progression or unacceptable toxicities. Between June 2002 and May 2004, 45 patients, of median age 57 years (range=38-73 years), were treated with the combination of capecitabine and paclitaxel. After a median 6 cycles (range=1-9 cycles) of chemotherapy, 43 were evaluable for toxicity and response. A total of 2 patients showed complete response and 20 showed partial response making the overall response rate 48.9% (95% CI=30.3-63.5%). After a median follow-up of 42.2 months (range=31.2-54.3 months), median time to progression was 5.6 months (95% CI=3.9-7.2 months) and median overall survival was 11.3 months (95% CI=8.1-14.4 months). Grade 3 or 4 adverse events include neutropaenia (46.5% of patients), hand-foot syndrome (9.3%), arthralgia (9.3%), and asthenia (4.7%). There was no neutropaenic fever or treatment-related deaths. Paclitaxel and capecitabine combination chemotherapy was active and highly tolerable as a first-line therapy for AGC.

A 78-year-old female underwent a curative total gastrectomy with D2 lymphandectomy for advanced gastric cancer in March 2003. S-1 mono-therapy (80 mg/m2, day 1-28/42 days) began as the first-line chemotherapy from October 2004 when multiple lung metastases were detected by CT. Paclitaxel mono-therapy (80 mg/m2, days 1, 8, 15/28 days) began as the second-line chemotherapy from April 2005 when prior S-1 mono-therapy judged as progressive disease (PD) by CT. Paclitaxel mono-therapy judged it as partial response (PR) in June, but the final judgement was as PD in September 2005. S-1 + CPT-11 combination therapy (S-1: 80 mg/m2, day 1-21, CPT-11: 80 mg/m2, days 1, 15/35 days) began as the third-line chemotherapy from September 2005. After 10 courses, multiple lung metastases were judged as complete response (CR) in September 2006. During the third-line chemotherapy, any adverse event of grade 2 or more did not occur. After judgment of CR, the patient has been followed without chemotherapy due to patient's desire, and is still alive without any recurrence in July 2007.

Paclitaxel (PTX), which is used for ovarian cancer, lung cancer, breast cancer and gastric cancer, is administered at a dose of 210 mg/m(2) once every three weeks. However, WHO grade 3-4 hematological and non-hematological toxicity occurred frequently in this manner. In recent studies about ovarian cancer and lung cancer, a schedule in which PTX was given weekly could have the same or better efficacy, with fewer side effects. The response rate of PTX administered every three weeks for gastric cancer, was 23.3 to approximately 28.0%, while that of PTX administered weekly was 24.0 to approximately 25.8%. Because of fewer adverse events, weekly PTX is widely used for gastric cancer in Japan. To prove the validity of PTX weekly administration, we performed a study using six specimens removed surgically and one specimen collected from ascites. A chemosensitivity test was performed on the basis of two assumptions: a high concentration for a short time, and a low concentration for a long time. A similar PTX effect was obtained when the AUC was equal. In this study, we demonstrated that the effect of low-dose PTX was equal to the effect of high-dose PTX in gastric cancer.

Paclitaxel(referred to hereinafter as PTX )is used in ovarian cancer, non-small cell lung cancer, breast cancer, gastric cancer, and endometrial cancer with positive treatment result reports. However, severe allergic reactions such as decreases in blood pressure and impaired breathing occur with relatively high frequency. For the prevention of such allergic reactions, administration of a premedication composed of the three components, dexamethasone sodium phosphate injection, diphenhydramine hydrochloride tablet, and ranitidine hydrochloride injection solution(or injectable famodine), is advised in the appended documentation. Administration is difficult because, among these three components, only diphenhydramine hydrochloride is administered orally and thus must be provided through the internal medicine department. Particularly when this combined dosage is administered as outpatient chemotherapy, the doctor must prescribe diphenhydramine hydrochloride tablets, and the patient must not forget to bring them on the day in which chemotherapy is administered. Also, checks by the medical staff such as pharmacists and nurses are required, complicating the administration of this therapy further. Taking this situation into consideration, our hospital uses a short-time premedication method wherein d-Chlorpheniramine Maleate injections are substituted for diphenhydramine hydrochloride tablets, and the time required for premedication is reduced to 15 minutes. This study investigated the allergic reaction ratio to consider the safety and usefulness of the short-time premedication method used at our hospital. The chemotherapy regimens conducted for the subject patients were 9 cases of PTX+CBDCA, 6 cases of biweekly- PTX, and 5 cases of weekly-PTX. A total of 67 PTX injections were given, 15 of them being first-time administrations. The ratio of allergic/hypersensitivity reactions was 10.0%(2 cases in 20). The short-time premedication method using d-Chlorpheniramine Maleate injections did not display a significant difference from the conventional method used for prevention of allergic and hypersensitivity reactions. Also, since this method of medication proves useful for is easy for the patient, reduces treatment time, is safe, economical, and helps reduce the workload of doctors, pharmacists, and nurses.

A 74-year-old male with advanced gastric cancer(cT3N1M0H0P0CY0, cStage III A)was treated with paclitaxel/ CDDP as neoadjuvant chemotherapy. Paclitaxel (80 mg/m(2)) and CDDP (25 mg/m(2)) were administered on days 1, 8 and 15 as one cycle. After the second course, a significant tumor reduction was obtained. Total gastrectomy, splenectomy, and D2 type nodal dissection were performed. The histological diagnosis revealed complete disappearance of cancer cells in the stomach and all of the lymph nodes, a so-called pathologically complete response. The patient has now been in good health without any recurrence for 9 months after surgery. This case suggests that neoadjuvant chemotherapy with paclitaxel/CDDP is a potential regimen for advanced gastric cancer.

This phase II study evaluated the efficacy and safety of combination chemotherapy with paclitaxel, cisplatin, and 5-fluorouracil (5-FU) in advanced gastric cancer. Patients with histologically confirmed gastric adenocarcinoma were eligible for the study. Paclitaxel (175 mg/m(2)) and cisplatin (75 mg/m(2)) were given as a 1-hr intravenous infusion on day 1, followed by 5-FU (750 mg/m(2)) as a 24-hr continuous infusion for 5 days. This cycle was repeated every 3 weeks. Forty-five eligible patients (median age, 56 yr) were treated in this way. Of the 41 patients in whom efficacy was evaluable, an objective response rate (ORR) was seen in 51.2% (95% CI, 0.35-0.67), a complete response in two, and a partial response in 19 patients. The median progression free survival was 6.9 months (95% CI, 5.86-7.94 months), and the median overall survival was 12.7 months (95% CI, 9.9-15.5). The main hematological toxicity was neutropenia and greater than grade 3 neutropenia was observed in twelve patients (54%). Febrile neutropenia developed in three patients (6.8%). The major non-hematological toxicities were asthenia and peripheral neuropathy, but most of patients showed grade 1 or 2. In conclusion, combination chemotherapy with paclitaxel, cisplatin, and 5-FU is a promising regimen, and was well tolerated in patients with advanced gastric cancer.

The prognosis of patients with T3 gastric cancer is poor, even if a curative resection is performed. Novel combination neo-adjuvant chemotherapy has been introduced for T3 gastric cancer patients. This pilot study involving 5 patients was performed between December 2002 and March 2003. They were diagnosed with gastric cancer with serosal invasion (T3) without P1 and CY1 by staging laparoscopy. We selected a combined chemotherapy with both paclitaxel and S-1. Paclitaxel at 60 mg/m2 was administered intraperitoneally on days 1 and 8, and S-1 at 80 mg/m2 was administered orally for 14 days followed by a 7-day-rest, as one course. After one course of this therapy, surgery was performed. The plasma concentration of paclitaxel was measured in two patients. Toxicites were generally mild, and no serious adverse reactions were observed. The plasma concentration of paclitaxel was about 100 ng/mL in the period of 1-6 hours after the administration. After one course, four patients underwent a total gastrectomy and one distal gastrectomy. The final histological stagings were included one stage IB, one stage II, one stage IIIA, one stage IIIB, and one stage IV. Three patients died at 10, 11, and 16 months after the initial treatment, and two have survived for 64 and 62 months. As the intraperitoneal administration of paclitaxel and oral S-1 was well-tolerated, further studies should be conducted involving T3 gastric cancer patients.

A 65-year-old male underwent a curative distal gastrectomy for advanced gastric cancer in June 2000. S-1 mono- therapy (80 mg/m2, day 1-28/42 days) for liver metastasis in S6 started as the first-line chemotherapy in October 2004. After 3 courses, complete response (CR) was observed for liver metastasis which had continued until January 2007. During the first-line chemotherapy, grade 2 non-hematological toxicities occurred and the S-1 dose reduction was required. Thereafter, no more grade 2 non-hematological toxicities were observed. Paclitaxel mono-therapy (80 mg/m2, day 1, 8, 15/28 days) for multiple lung metastases started as the second-line chemotherapy in February 2007. After 4 courses, complete response (CR) was observed for lung metastasis which has continued until now, May 2008. During the second- line chemotherapy, grade 3 neutropenia and grade 2 leukopenia occurred and a 10% dose reduction of paclitaxel was required three times. Consequently, the hematological toxicities have not occurred.

Advanced or metastatic gastric cancer, which is one of the most common malignancies in Korea, is difficult to cure by surgery alone and generally requires combination chemotherapy. Paclitaxel is active against gastric cancer and when combined with 5-fluorouracil/leucovorin and/or cisplatin is effective in the treatment of gastric cancer. We attempted to determine the effect and safety with the combination of paclitaxel with split cisplatin and 5-fluorouracil/leucovorin in advanced or metastatic gastric cancer. Patients with histologically-proven locally advanced/metastatic or recurrent gastric cancer with an ECOG performance status 0-2 were enrolled. The patients received 135 mg/m(2) of paclitaxel as a 3-h intravenous infusion on day 1 and 5-fluorouracil (1200 mg/m(2)) plus leucovorin (20 mg/m(2)) as an intravenous infusion over 12 h plus cisplatin (30 mg/m(2)) by continuous intravenous infusion on days 1-3, every 21 days. Between September 2003 and April 2005, 30 patients (26 evaluable patients) with a median age of 57 years (range 34-74) were enrolled and underwent 111 completed treatment cycles (a median of 3 cycles per patient). Of the evaluable patients, 12 patients showed a partial response and 8 patients had stable disease. The overall response rate was 46.2%. The median progression-free survival was 5.6 months (95% CI. 3.76-7.4 months), and the median overall survival was 9.6 months (95% CI. 6.67-12.47 months). The hematologic and non-hematologic toxicities were tolerable. The grade III and IV hematologic toxicities were anemia (6.8%) and neutropenia (2.6%). Febrile neutropenia was observed in 1 patients and 1 cycle. Other hematologic toxicities and grade III and IV non-hematologic toxicities, except nausea (66.7%) and vomiting (33.3%) were uncommon and not severe. TPFL combination chemotherapy is effective and tolerable with acceptable toxicities in patients with advanced/metastatic, recurrent gastric cancer.

A 68-year-old man underwent total gastrectomy for Type 3 gastric cancer with liver metastasis. The final finding was T3(SE), N1, H1, P0, CY0(class IV), Stage IV, Cur C. After surgery, he was treated with combination chemotherapy of weekly paclitaxel(PTX)/doxifluridine(5'-DFUR). Paclitaxel was administered at a dose of 80 mg/m(2) on day 1, 8 and 15, and doxifluridine was orally administered at a dose of 533 mg/m(2) day for five days followed by withdrawal for two days. This regimen was repeated every four weeks. After 2 courses, the tumor marker level normalized, and the size of the liver metastasis was remarkably decreased. After 5 courses, a CT scan revealed the liver metastasis had disappeared, and he has now survived without recurrence after the disappearance of the liver metastasis. No severe adverse reactions were observed, and the man can be treated as an outpatient. This therapy may thus be effective in the treatment of advanced gastric cancer following non-curative operation.
