A phase I study to determine the maximum tolerated dose and toxicity of gemcitabine when given as a 24 h infusion to patients with inoperable non-small-cell lung cancer (NSCLC). A total of 24 patients with unresectable stage IIIa-IV NSCLC were entered into the study. Gemcitabine was administered as a 24 h infusion on days 0, 7 and 14. Courses of therapy were repeated every 28 days. There were 16 males and 8 females with a median age of 51 years (range 40-73 years). The WHO performance score was 1 (21 patients) or 2 (3 patients). The TNM stage was IIIa (6), IIIb (10) and IV (8). Three patients were entered at each dose level with six at the maximum tolerated dose (MTD). Dose levels were 10, 20, 40, 80, 120, 180 and 210 mg m-2. The MTD was 180 mg m-2 and dose-limiting toxicity was neutropenia and lethargy. Partial response was observed in five (21%) patients (95% CI 7-42%) lasting 10, 14, 18, 47 and 51 + weeks. The maximum tolerated dose of gemcitabine given as a 24 h infusion was 180 mg m-2.

Platinum compounds and vinorelbine have been demonstrated to be active in non-small-cell lung cancer (NSCLC). The aims of the study were to assess tolerability and feasibility of increasing doses of carboplatin (level 1: 300 mg/ m2 on day 1, level 2: 350 mg/m2 on day 1, level 3: 400 mg/m2 on day 1) in combination with a fixed dose of vinorelbine (25 mg/m2 on days 1 and 8) in advanced NSCLC. Forty-two patients entered the study and were evaluable for toxicity and response. The patients were not treated using systemic chemotherapy, had TNM stage IIIB-IV, performance status ECOG 0-2, and their median age was 62 (range 41-70) years. The number of patients evaluable for each dose level was 14. A total of 138 (median 3) courses was administered. Nonhematologic side effects included grade I-II mucositis (9%), neurotoxicity (6%), and infections (4%). Myelotoxicity was manageable and generally of short duration, with 19% of the patients having grade III-IV neutropenia. No significant difference was observed for the three treatment groups. No drug-related death was observed. An objective remission was observed in 10 patients (24% response rate; 95% confidence interval 12-39%), with 5 responses in 14 patients treated with the 400-mg/m2 dose. In conclusion, the combination of carboplatin at a dose of 400 mg/m2 on day 1 and vinorelbine at a dose of 25 mg/m2 on days 1 and 8 can be safely administered as first-line cytotoxic therapy in advanced NSCLC and warrants further evaluation.

In order to downstage locally advanced breast cancer, neoadjuvant chemotherapy consisting of intravenous vinorelbine 25 mg/m plus epirubicin 75 mg/m given on day 1 and oral vinorelbine 60 mg/m on day 8 was administered every 3 weeks for four courses. On day 2, all patients received a single subcutaneous injection of pegfilgrastim (6 mg). From March 2004 to June 2005, 22 patients were enrolled. Patients characteristics were: median age, 53 years (range: 39-70 years); postmenopausal, 7/22; clinical TNM stage, T2 (n=14), T3 (n=8), N0 (n=17) and N1 (n=5). The median number of courses was four (range: two to six courses) with full dose intensity. National Cancer Institute grade 3 haematological toxicities observed were neutropenia in 9% of patients, anaemia in 13% of patients and thrombocytopenia in 9% of patients; no toxicity grade 4 occurred. Two patients (9%) registered grade 2 polyneuropathy; no cardiac failure was observed. Conservative surgery was performed in 14 patients (63%). All patients were evaluable for response: complete pathological response was documented in three patients (13.6%); three patients (13.6%) obtained more than 75% of tumour size reduction; 11 other patients (50%) had 50% of tumour size reduction; stable disease was observed in five patients (22.7%). The present findings indicate that vinorelbine in combination with epirubicin is an effective and safe treatment in locally advanced breast cancer: this regimen obtained more than 50% of tumour size reduction in 77% of patients; the use of pegfilgrastim allowed full dose intensity. Oral vinorelbine on day 8 offers greater convenience to the patient by reducing the need for intravenous injection and the time spent in hospital.

Rhabdomyosarcoma is the most common sarcoma of childhood. Fortunately, the goal of cure is realistic for the majority of patients with localized tumors. However, management of these patients remains challenging. The fact that the tumor arises in a wide variety of primary sites, some of which are associated with specific patterns of local invasion, regional lymph node spread, and therapeutic response, requires physicians to be familiar with site-specific staging and treatment details. In addition, rhabdomyosarcoma requires multimodality therapy that can be associated with significant acute toxicities and long-term effects, particularly when administered to young children. These factors sometimes present a dilemma as to the best approach to optimize the chance of cure, minimize toxicity, and respect quality of life. The purpose of this review is to discuss 'optimal' management of this complicated tumor. Since the tumor is relatively rare, requires highly specialized care, and important management questions remain to be answered, optimal management of rhabdomyosarcoma includes enrollment in clinical trials whenever possible. Appropriate management begins with establishing the correct pathologic diagnosis, histologic subtype, primary site, extent of disease (International Society of Pediatric Oncology [SIOP]-TNM-Union Internationale Contre le Cancer stage or Intergroup Rhabdomyosarcoma Study Group [IRSG] stage), and extent of resection (IRSG group). Cooperative groups throughout North America and Europe have defined risk-adapted treatment based on these factors; this treatment requires a coordinated management plan that includes surgery, chemotherapy, and usually radiotherapy. The surgical approach for rhabdomyosarcoma is to excise the primary tumor whenever possible without causing major functional or cosmetic deficits. Wide excision is difficult in some primary sites and can be complicated by the fact that the tumor grows in a locally infiltrative manner so that complete resection is often neither possible nor medically indicated. Incompletely resected tumors are generally treated with radiotherapy. The cooperative groups reduce the dose of radiation based on the response of the tumor to chemotherapy and delayed primary resection to differing degrees. Response-adjusted radiation administration may reduce the long-term effects of radiotherapy, such as bone growth arrest, muscle atrophy, bladder dysfunction, and induction of second malignant neoplasms; however, it may also be associated with an increased risk of tumor recurrence. All patients with rhabdomyosarcoma require chemotherapy. A backbone of vincristine and dactinomycin with either cyclophosphamide (VAC) or ifosfamide (IVA) has been established. Risk-adapted treatment involves reducing or eliminating the alklyating agent for patients with the most favorable disease characteristics. Clinical trials are ongoing to improve outcomes for higher risk patients; newer agents, such as topotecan or irinotecan, in combination with VAC or use of agents in novel ways are being investigated. Acute and long-term toxicities associated with these chemotherapy regimens include myelosuppression, febrile neutropenia, hepatopathy, infertility, and second malignant neoplasms. A 5-year survival rate >70% has been achieved in recent trials for patients with localized rhabdomyosarcoma. However, the outcome for patients who present with metastatic disease remains poor. In the future, risk-adapted classification of rhabdomyosarcoma will likely be based on biologic features, such as the presence of chromosomal translocations or specific gene expression profiles. It is hoped that newer therapies directed at specific molecular genetic defects will benefit all patients with rhabdomyosarcoma.

Encouraging response rates and survival have been reported with intra-arterial (i.a.) chemotherapy and chemoembolization, but limited data are available on the association of the two treatment modalities. We therefore started a feasibility study of i.a. chemotherapy plus chemoembolization, performed every 28 days for 3 cycles, according to the following schedule: L-leucovorin (100 mg/m(2) i.v.), fluorouracil (800 mg/m(2) i.a.), and carboplatin (250 mg/m(2) i.a.). Chemoembolization with mitoxantrone (10 mg/m(2)) plus ethiodized oil was performed immediately after this treatment, followed by gelatin powder. Fourteen patients entered the study and were evaluable for side effects. Main patient characteristics were: males 13, females 1; median age 65 yr (range 45-75); stage TNM II-III 10, IVA 4; Childs' A 8, Childs' B 6; elevated baseline alpha-fetoprotein, 11; cirrhosis 14. No drug-related deaths have been observed. Ten patients were able to complete the program. The reasons for discontinuing treatment were worsening of liver functions in 3 cases and grade IV neutropenia in 1 patient. Eight patients had grade I-II pain and 10 patients had grade I-II fever. In conclusion the study demonstrated that chemoembolization plus i.a. chemotherapy is feasible in patients with hepatocellular carcinoma in cirrhosis and deserves further investigation.

The combination of docetaxel, cisplatin, and 5-fluorouracil (DCF) as preoperative treatment for esophageal squamous cell carcinoma (ESCC) has not been investigated. We carried out a multicenter phase II feasibility study of preoperative chemotherapy with DCF for ESCC. Patients with clinical stage II/III ESCC (International Union Against Cancer TNM classification system, 6th edition) were eligible. Chemotherapy consisted of i.v. docetaxel (70-75 mg/m(2)) and cisplatin (70-75 mg/m(2)) on day 1, and continuous infusion of fluorouracil (750 mg/m(2)/day) on days 1-5. Antibiotic prophylaxis on days 5-15 was mandatory. This regimen was repeated every 3 weeks with a maximum of three cycles allowed. After completion of chemotherapy, esophagectomy with extended lymphadenectomy was carried out. The primary endpoint was the completion rate of protocol treatment. Forty-two eligible patients were enrolled. During chemotherapy, the most common grade 3 or 4 toxicities were neutropenia (83%), anorexia (7%), and stomatitis (5%). Forty-one (98%) patients underwent surgery. The completion rate of protocol treatment was 90.5% (38/42). No treatment-related death was observed and the incidence of operative morbidity was tolerable. According to RECIST, the overall response rate after the completion of DCF was 64.3%. Pathological complete response was achieved in 17%. The estimated 2-year progression-free survival and overall survival were 74.5% and 88.0%, respectively. Although these data are preliminary, preoperative DCF was well tolerated. Antitumor activity was highly promising and warrants further investigation. This trial was registered with University Hospital Medical Information Network (no. UMIN000002396).

Carcinoma of the penis is rare, and the prognosis of penile cancer with inguinal metastases is extremely poor. Standard chemotherapy for advanced penile cancer has not been established because of its rarity. A case of penile cancer with inguinal metastases that responded well to neoadjuvant chemotherapy with paclitaxel, ifosfamide and cisplatin (TIP) is described. A 55-year-old Japanese male visited our hospital for a penile tumor and fixed, 4 cm, right inguinal lymph nodes. Computed tomography and 18F-FDG-PET imaging showed not only right but also left inguinal lymphadenopathy. Penile cancer (clinical stage T3N3M0, 7th edition TNM classification) was diagnosed, and partial penectomy and right inguinal biopsy were performed. The pathological examination revealed squamous cell carcinoma of the penis with right inguinal lymph node metastasis. The inguinal metastases were judged to be unsuitable for radical resection ; and, paclitaxel 60 mg/m2 (day 1), ifosfamide 1,200 mg/m2 (days 1-3), and cisplatin 60 mg/m2 (days 1-3) were given at 3-week intervals as neoadjuvant chemotherapy. After 4 courses of chemotherapy, the inguinal metastases were markedly reduced. He had neutropenia (grade 3) during each course and peripheral neuropathy after 2 courses, but there were no severe complications. The patient underwent bilateral inguinal and pelvic lymphadenectomy after neoadjuvant chemotherapy. Pathological examination revealed no viable cells in the resected specimens. The patient remains alive and well with no evidence of recurrence 8 months after this radical treatment. TIP chemotherapy appears to be effective for advanced penile cancer.

- Chronic inflammation has been linked with many cancers. It seems that easily available and usual blood inflammatory markers might serve as a prognostic factor for overall survival and disease-free survival in patients with various cancers. Preoperative neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR), as well as hemoglobinemia, thrombocytosis, elevated C-reactive protein values, neutropenia and leukocytosis have been shown to affect overall survival and disease-free survival in patients with colorectal cancer (CRC), however, with controversial results. Complete blood count, NLR and PLR were determined in 71 patients with CRC (stages 3 and 4) after neoadjuvant chemo-radiotherapy and before surgery, treated at Hospital for Tumors in Zagreb. Statistical analysis included Mann-Whitney U test, Student's t-test, univariate and multivariate analysis. The results of Mann-Whitney U test and Student's t-test showed that neutrophil count (p=0.024), NLR (p=0.003) and PLR (p=0.007) correlated significantly with overall survival. However, there was no significant correlation of age, leukocyte, lymphocyte and platelet counts and hemoglobin values with overall survival of patients. Furthermore, the same tests showed that leukocyte (p=0.04), neutrophil (p=0.0014) and platelet (p=0.006) counts, NLR (p=0.0006) and PLR (p=0.0015), as well as hemoglobin values (p=0.028) correlated significantly with disease-free survival. The results of univariate analysis showed that unlike PLR, NLR correlated with overall survival and disease-free survival (p=0.0002), although the correlation of PLR and disease-free survival almost reached significance (p=0.059). Furthermore, the results of univariate analysis showed significant correlation of advanced pathological TNM stage with overall survival. There was no correlation of patient age and gender, tumor stage and neoadjuvant chemo-radiotherapy with overall survival and disease-free survival. The results of multivariate analysis showed that NLR (cut-off value 3.27) and advanced pathological TNM stage significantly correlated with disease-free survival but not with overall survival. It seems that NLR might be an accurate marker for overall survival and disease-free survival in CRC patients after neoadjuvant chemo-radiotherapy and before surgery.
