[Incidence and mortality due to cancer in Navarre, 1998-2002. Trends in the last 30 years]. / Incidencia y mortalidad por cáncer en Navarra, 1998-2002. Evolución en los últimos 30 años.

Between 1998-2002, 16,952 new cases of cancer were registered in Navarre. In men, the most frequently diagnosed cancers were in the following order: prostate, lung, colon and rectum, bladder and stomach, which accounted for 63.2%. In women, the sites were breast, colon and rectum, corpus uteri, stomach and ovary, which accounted for 57.6% of the cases. In the same period, 1998-2002, 4,127 men and 2,470 women died from cancer. Sixty percent of all deaths due to malign tumours in men were due to cancer of the lung, prostate, colon and rectum, stomach and bladder. In women this was due to cancers of colon and rectum, breast, stomach, pancreas and lung, which accounted for 49% of the cases. In men in Navarre there has been an increase in the incidence rates of cancer of the prostate, kidney and non-Hodgkin lymphoma. Avoidable cancers such as those related to smoking (lung, oral cavity and pharynx or pancreas) continue to rise, and represent a greater global risk of dying from cancer in the latest period studied than in the decades of the 1970s and 1980s. From 1995 up to the present, mortality due to cancer has moved from occupying the second place to become the first cause of death among men in Navarre. The global risk of death due to cancer in men is now equal to the first period studied, 1975-1977. Amongst women the global risk of death due to cancer fell by 25% between 1975 and 2002, basically at the cost of breast and stomach cancer. Tumours related to smoking increased both in mortality and in incidence and appear as a significant health problem amongst women in Navarre. Breast cancer has increased in incidence, with lower mortality figures than those of the first period 1975-1977. Invasive cancer of the cervix remains at very low rates in comparison with many European countries, including Spain. In both sexes colorectal and skin cancer has increased, while the incidence and mortality of stomach cancer continues to fall.

Hyperfractionated radiotherapy concomitant with cisplatin and granulocyte colony-stimulating factor (filgrastim) for laryngeal carcinoma.

An open-label, non-randomized study evaluated the feasibility and efficacy of filgrastim (recombinant methionyl human granulocyte colony-stimulating factor, r-metHuG-CSF) to prevent mucositis induced by accelerated hyperfractionated radiotherapy (1.6 Gy b.i.d., total dose 67.2 Gy in six weeks with a two-week split) and concomitant chemotherapy (cisplatin, 20 mg/m2/day, days 1-5 by continuous intravenous infusion) in patients with laryngeal carcinoma. Filgrastim 300 microg/day was administered on days 1, 3, and 5 in weeks 2-6 of radiotherapy, after the second fraction. Twenty patients (three stage II, six stage III, and eleven stage IV, according to AJCC) were enrolled in the trial. Oral mucosal toxicity was grade 2 in nine patients (45%), grade 3 in eight (40%), and grade 4 in three (15%). Severe hematological toxicity (WHO criteria) was uncommon. Nineteen patients (95%) completed the treatment in the planned time. Overall survival was 55% at three years. The administration of filgrastim with this regimen was feasible, and it appeared to reduce the severity and duration of mucositis induced by the combined treatment.

[Quality of Life of cancer patients: studies by the Oncology Department of the Hospital of Navarra in the Quality of Life Group of the EORTC]. / La Calidad de Vida en el paciente oncológico: estudios del Servicio de Oncología del Hospital de Navarra en el Grupo de Calidad de Vida de la EORTC.

The Quality of Life of cancer patients and its assessment are of great important nowadays. They are useful in offering a treatment that is better adapted to the characteristics of the patient and the development of his/her illness. Patients have to evaluate their Quality of Life through measurement instruments. The European Organisation of Research and Treatment of Cancer-EORTC is an international body devoted to research in cancer treatment. One of its divisions is working on the study of the Quality of Life. They have developed a core questionnaire for Quality of Life measurement and modules for different types of tumour and treatment to complement this. The Oncology Department of the Hospital of Navarra has been collaborating in this group since 1992. The Department has participated in the creation or validation of the core questionnaire and different modules. It is measuring the Quality of Life in different clinical studies. All members of the department are collaborating in these studies.

Radical chemoradiotherapy for elderly patients with bladder carcinoma invading muscle.

BACKGROUND: Chemoradiotherapy is becoming an alternative to radical cystectomy among patients with bladder carcinoma invading muscle. In 1988, the authors began a protocol with methotrexate, vinblastine, doxorubicin, and cisplatin (M-VAC regimen) and radiotherapy for these patients. Traditionally, age has been considered a determinant factor thereby excluding the older patients from the oncologic protocols that are considered to be more aggressive. The authors analyzed 20 patients (age > 70 years) who were treated during this period with the same protocol as the authors' other patients. METHODS: The study included 20 patients (age range, 70-78 years; median age, 74 years) including 4 patients with T2 disease, 9 with T3 disease, and 7 with T4 disease. All patients had a Karnofsky performance status of > 60. Treatment protocol included cytoreductive transurethral resection, 2 cycles of M-VAC chemotherapy, and radiotherapy (45 grays [Gy] on pelvic volume) with concurrent cisplatin (20 mg/m2 on Days 1-5. Response was determined by cystoscopic evaluation. If there was a complete response, radiotherapy continued until a total dose of 65 Gy; if there was not a complete response, cystectomy was performed. RESULTS: Tumor response after a dose of 45 Gy included 11 complete responses (55%), 5 partial responses (25%), and 4 nonresponses (20%). Overall survival was 75%, 34%, and 27% in the 2nd, 3rd, and 5th years of follow-up, respectively. Cause specific survival was 79%, 54%, and 38%, respectively. Survival for patients with complete response was 100%, 60%, and 48%, respectively. Severe toxicity was uncommon, with the most frequent toxicities being leukopenia and cystitis. No treatment-related death occurred with either treatment protocol. CONCLUSIONS: The age of the individual must not become a strict exclusion criterion for the radical treatment of old patients with invasive bladder carcinoma.

Mitomycin, cisplatin, and vindesine followed by radiotherapy combined with cisplatin in stage III nonsmall cell lung cancer: long-term results.

PURPOSE: To assess the tolerance, response rate, pattern of failure, and long-term survival of patients with unresectable nonsmall cell lung cancer treated with one cycle of induction chemotherapy followed by concurrent cisplatin and radiotherapy. METHODS AND MATERIALS: From 1986 to 1988, 45 patients with histologically proven nonsmall cell lung cancer clinical Stage III (29 IIIA and 16 IIIB) were included in this study. Patients received one cycle of Mitomycin C 10 mg/m2 day 1, Cisplatin 120 mg/m2 day 1, and Vindesine 3 mg/m2 days 1, 8, 15, and 22, by i.v. bolus injection. Radiotherapy was started within 4-6 weeks after completion of chemotherapy, with a total tumor dose of 60 Gy, at 2 Gy/day. Cisplatin, 20 mg/m2/day by i.v. continuous infusion was administered for days 1-5 of radiation treatment. RESULTS: The main toxic acute effects were nausea-vomiting grade 1-3 in 38 patients (85%). Ten patients (22%) developed esophagitis grade 3. Leukopenia grade 1-2 was observed in 18 patients (40%), grade 3 in 12 (27%), and grade 4 in 4 (9%). Three patients (6.6%) died by granulocytopenia and sepsis. A bronchoscopic proven complete response was achieved in 9 patients (21.5%) and partial response in 28 patients (67%). With a minimum follow-up of 65 months, overall median survival was 13 months, 2-year survival was 21%, and 5-year survival was 7%, with no statistical difference between Stage IIIA and IIIB. Median survival of patients with complete response was 23.2 months, and 5-year survival was 33%. CONCLUSION: This treatment scheme produced a severe toxicity and in spite of a high response rate, long-term survival is poor, similar to previous studies with radiotherapy alone.

Neoadjuvant chemotherapy and radiotherapy in locally advanced esophagus carcinoma: long-term results.

PURPOSE: A prospective study with neoadjuvant chemotherapy and radiotherapy in patients with locally advanced esophagus carcinoma for evaluating: toxicity, response rate, pattern of recurrence, and survival after a long follow-up. METHODS AND MATERIALS: Between 1983-1988, 40 patients with locally advanced squamous cell carcinoma of the thoracic esophagus were entered into a prospective trial of neoadjuvant chemotherapy and radiotherapy. Eight patients (20%) were Stage II and 32 patients (80%) were Stage III, according to American Joint Committee staging criteria. Neoadjuvant chemotherapy consisted of two cycles with cisplatin (120 mg/m2 day 1), vindesine (3 mg/m2 days 1, 8, 15, and 22) and bleomycin (10 mg/m2 days 3 to 6). Second cycle was initiated on day 29. Radiation therapy was administered 2-4 weeks after completion of chemotherapy, with a total dose on tumor of 60 Gy. RESULTS: Two patients died from treatment-related toxicity. Complete response was observed in 20 patients (53%) and symptomatic improvement in 31 patients (82%). The median survival was 11 months, with an actuarial survival at 1 year of 45%, 3 year 20%, and 5 years 15%. Significantly (p < 0.05) longer survival was observed in patients with Stage II (median survival 18 months) vs. Stage III (median survival 10 months). The pattern of failure was predominantly local/regional (62%). CONCLUSION: This treatment scheme is an effective and tolerable regimen but long-term survival was poor.

The antiemetic efficacy of thiethylperazine and methylprednisolone versus thiethylperazine and placebo in breast cancer patients treated with adjuvant chemotherapy (fluorouracil, doxorubicin and cyclophosphamide). A randomized, double-blind, cross-over trial.

Forty-six women with breast cancer treated with adjuvant FAC (fluorouracil, doxorubicin and cyclophosphamide) entered a multicenter, randomized, double-blind, cross-over trial in which thiethylperazine (T) (6.5 mg p.o every 8 h x 3 days) plus methylprednisolone (MP) (250 mg i.v. x 2 doses) was compared with thiethylperazine plus placebo. Forty-four patients were evaluable for efficacy. T + MP was significantly better in reducing vomiting (p less than 0.01) and nausea (p less than 0.02). The complete protection rate against vomiting was 36% for T + MP compared to 18% for T + placebo, and the percentage of nausea grades 0 + 1 (none or slight) was 59% and 27% respectively. The patient preference after cross-over was strikingly in favor of T + MP (70% versus 13%) (p less than 0.001). The most important side-effects of T + MP were facial flushing (22%) and euphoria (27%). Other side-effects, such as dryness of the mouth and sedation, were common after both treatments. In conclusion, the study suggested that T + MP is superior to T alone in protecting from nausea and vomiting induced by FAC.
