ABSTRACT: Cetuximab plus radiotherapy (RT) may be an effective alternative to chemoradiation in locally advanced head and neck squamous cell carcinoma (LASCCHN) patients. We analyzed a group of patients treated at our institute with cetuximab plus volumetric modulation arc therapy (VMAT) with the RapidArc technique in a simultaneous integrated boost (SIB) regime. The primary end point was the assessment of acute toxicity and the feasibility of the combined approach.
Between December 2008 and March 2010, 22 patients were submitted to IMRT-SIB plus cetuximab for radical intent in case of LASCCHN. None of the patients was suitable for chemotherapy because of important comorbidities (the majority suffered of heart chronic diseases). All patients underwent planning CT (additional image modalities were acquired for contouring purposes in the same treatment position: MRI in 12 and FDG-PET in 4 out of 22 patients). VMAT, by means of RapidArc, and SIB with two dose levels of 54.45 Gy and 69.96 Gy in 33 fractions were adopted. All patients included in the analysis were concomitantly treated with cetuximab: administration of the drug was initiated 1 week before RT at a loading dose of 400 mg/m(2) body surface area over a period of 120 min, follow by a weekly 60 min infusion of 250 mg/m(2) for the duration of RT. Patients were assessed for toxicities according to the Radiation Therapy Oncology Group (RTOG) criteria.
All but 2 patients completed treatment and achieved the minimum follow-up of 12 months after the end of the treatment. Of the 22 patients, 18% (4 patients) showed grade 1, 36% (8 patients) grade 2, and 36% (8 patients) showed grade 3 dermatitis, while 9% (2 patients) had grade 1, 36% (8 patients) grade 2, and 45% (10 patients) had grade 3 mucositis/stomatitis. No grade 4 toxicities were recorded. Considering blood parameters, 3 cases of grade 1 anemia and 1 case of grade 2 thrombocytopenia were observed. Nobody required feeding tube placement during treatment.
The here reported toxicity data are promising and encouraging in regard to the adoption of moderate hypofractionation with VMAT-SIB techniques, when cetuximab is concomitantly administered.

ABSTRACT: The purpose of this study is to investigate the prognostic role of insulin-like growth factor receptor 1 (IGF1R) expression in surgically resected non-small-cell lung cancer (NSCLC). Patient characteristics and methods: This retrospective study was conducted in 369 stage I-II-IIIA, surgically resected, NSCLC patients. Patients exposed to anti-epidermal growth factor receptor (EGFR) agents were excluded. IGF1R expression was evaluated by immunohistochemistry in tissue microarray sections.
A positive IGF1R expression (score > or = 100) was observed in 282 cases (76.4%) and was significantly associated with squamous cell histology (P = 0.04) and with grade III differentiation (P = 0.02). No difference in survival was observed between the positive and negative group when score 100 was used as cut-off for discriminating a positive versus a negative IGF1R result (52 versus 48 months, P = 0.99) or when median value of IGF1R expression was used (45 versus 55 months, P = 0.36). No difference in survival was observed between IGF1R-positive and -negative patients in a subgroup of stage I-II adenocarcinoma (n = 137) with known EGFR mutation and copy number status.
IGF1R expression does not represent a prognostic factor in resected NSCLC patients. Patients with squamous cell carcinoma overexpress IGF1R more frequently than patients with nonsquamous histology, justifying the different sensitivity to anti-IGF1R agents observed in clinical trials.

ABSTRACT: Gefitinib ('Iressa', ZD1839) is an orally active epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor that has demonstrated antitumour activity and favourable tolerability in Phase II studies. We investigated whether EGFR expression levels could predict for response to gefitinib in patients with advanced non-small-cell lung cancer (NSCLC), who received gefitinib (250 mg day(-1)) as part of a worldwide compassionate-use programme. Tissue samples were analysed by immunohistochemistry to assess membrane EGFR immunoreactivity. Of 147 patients enrolled in our institution, 50 patients were evaluable for assessment of both clinical response and EGFR expression. The objective tumour response rate was 10% and disease control was achieved in 50% of patients. Although high EGFR expression was more common in squamous-cell carcinomas than adenocarcinomas, all objective responses were observed in patients with adenocarcinoma. Response and disease control with gefitinib were not associated with high EGFR expression. Overall, median survival was 4 months, and the 1-year survival rate was 18%. Strong EGFR staining correlated with shorter survival time for all patients. Gefitinib demonstrated promising clinical activity in this group of patients with NSCLC. These results have also shown that EGFR expression is not a significant predictive factor for response to gefitinib.

ABSTRACT: Gefitinib (Iressa(TM), ZD1839) is an orally active, selective epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor. Phase I studies showed that it is well tolerated, with evidence of tumor regression in patients with advanced non-small-cell lung cancer (NSCLC). Therefore, we aimed to assess the antitumor activity and tolerability of gefitinib in a series of patients with previously treated, advanced NSCLC, as a part of a compassionate use program.
To be eligible, all patients were required to have histologically or cytologically proven advanced or metastatic NSCLC, prior chemotherapy with at least one cisplatin-containing chemotherapy regimen or contraindication to cytotoxic drugs, Eastern Cooperative Oncology Group performance status < or =2, and adequate hematological, renal and hepatic parameters. All patients provided signed informed consent. Patient re-evaluation was performed every 4-6 weeks.
Seventy-three consecutive patients were enrolled. Response rate, including complete and partial response, was 9.6%; an additional 43.8% of patients achieved stable disease, for an overall disease control of 53.4%. EGFR1 status was evaluated by immunocytochemistry in 25 patients. According to EGFR1 immunoreactivity all responses were observed with medium/strong imunoreactivity while three out of four responses were observed in high expressive patients. Median survival for all patients was 4 months while it reached 6 months for patients with disease control. The 1-year survival rate was 13.1% for the entire series and 23.2% for patients with disease control. Non-hematological toxicity was generally mild.
Gefitinib has promising activity with a good toxicity profile in patients with progressive NSCLC who have received one or two prior chemotherapy regimens. A possible relationship within response and EGFR1 expression is suggested.

ABSTRACT: To study prospectively the activity of primary chemotherapy with cisplatin, fluorouracil and leucovorin (PFL) in patients with paranasal cancer receiving surgery and postoperative radiotherapy.
Forty-nine patients, previously untreated, with resectable paranasal carcinoma were enrolled. PFL (leucovorin 250 mg/m2/day for 5 days as a 120 h continuous infusion (c.i.), 5-fluorouracil 800 mg/m2/day from day 2 as a 96 h c.i. and cisplatin 100 mg/m2 day 2 q 3 weeks) was planned for five courses.
Thirty-two patients (65%) completed three or more chemotherapy courses. Two deaths from thrombotic events were observed after the first cycle. Eight cardiac toxicities were recorded during chemotherapy causing treatment discontinuation. Objective response to PFL was observed in 21 patients [43%; 95% confidence interval (CI) 29% to 58%], including four complete responses (CRs) (8%; 95% CI 2% to 20%) and 17 partial responses (PRs) (35%). Pathological complete remission (pCR) was achieved in eight of 49 patients (16%). At 3 years, overall survival was 69% and event-free survival 57%. Overall and event-free survival in patients achieving pCR is 100%.
PFL is active in paranasal cancer. Patients who attain a pathological complete remission have a favorable prognosis. Cardiovascular complications represent the limiting toxicity. Primary chemotherapy combined with surgery-sparing treatment approaches deserves further investigation.

ABSTRACT: The cisplatin and gemcitabine (GC) regimen is usually administered as a 4- or 3-week schedule; however, the best schedule to use is still unclear. We therefore started a randomized phase II trial to compare toxicity and dose intensity (DI) between these two GC schedules.
Ninety-six patients with non-small-cell lung cancer (NSCLC) and an additional 11 patients with an advanced epithelial neoplasm [bladder (n = 5), head and neck (n = 3), cervix (n = 1), esophageal (n = 1) or unknown primary carcinoma (n = 1)] were randomized to receive cisplatin 70 mg/m(2) intravenously on day 2 plus either gemcitabine 1000 mg/m(2) on days 1, 8 and 15 of a 28-day cycle or gemcitabine 1000 mg/m(2) on days 1 and 8 of a 21-day cycle. Planned DI (PDI) for the 4-week schedule was 750 mg/m(2)/week for gemcitabine and 17.5 mg/m(2)/week for cisplatin; for the 3-week regimen PDI was 666 mg/m(2)/week and 23 mg/m(2)/week for gemcitabine and cisplatin, respectively.
From July 1998 to March 2000, 107 patients were randomized. Grade 3/4 neutropenia was observed in 27.8% of patients in the 3-week versus 22.5% in the 4-week arm (P = 0.69), while grade 3/4 thrombocytopenia was higher in the 4-week arm (29.5% versus 5.5% of patients; P = 0.14). A total of 398 cycles of therapy were delivered. Overall, 51% of cycles were modified in dose, timing or both in the 4-week arm, and 19% in the 3-week arm. The 21-day schedule of GC leads to a similar received DI of gemcitabine and higher cisplatin DI. Both regimens had activity in NSCLC, with a response rate of 39% (38% for the 4-week arm, and 42% for the 3-week arm).
The 3-week schedule has similar DI to the 4-week schedule. However the 3-week regimen has a better compliance profile and a comparable response rate in NSCLC, supporting the use of such a schedule.

ABSTRACT: This study included patients with inoperable primary or recurrent cervical cancer whose treatment plan called for exclusive radiotherapy. The endopoints of the study were to confirm the feasibility of concurrent radiotherapy and paclitaxel in relation to potential acute toxicity and to evaluate if an increase of complete local control might be obtained with the association of paclitaxel to radiotherapy as a radiosensitizer.
Twenty patients (13 new cases, stage IIB-III, and 7 with pelvic recurrences) were enrolled and, with exclusion of one recurrence, 19 were evaluable for acute toxicity and response. In new cases, radiotherapy was conventionally administered: 50.4 Gy/28 fractions by external beam (whole pelvis) followed by intracavitary cesium or reduced transcutaneous field. In recurrences, radiotherapy was performed with external beam only through individualized fields. Paclitaxel was administered weekly at the dose of 40 mg/m2 or 60 mg/m2 during the entire course of external radiotherapy.
Complete regression (CR) as defined by clinical and imaging examinations was achieved in eight of the 13 new cases (62%) and in four of the six recurrences (66%), for a total complete response rate equal to 63%. Five patients (3 treated with 40 mg/m2 and 2 with 60 mg/m2) experienced grade 3 small bowel toxicity, one patient treated with 40 mg/m2 grade 3 bladder toxicity and one patient treated with 60 mg/m2 had grade 4 mucositis. Out of 12 CR patients at the end of treatment, ten maintain complete local remission for a median follow-up of 47 months but two have developed distant metastases.
The results confirm that this approach is feasible and suggest the use of paclitaxel as radiosensitizer in locally advanced cervical cancer.

ABSTRACT: The predictive role in terms of pathological response and prognostic role of biomarkers such as GST-pi, p53, bcl-2 and bax expression, immuno-histochemically detected, and of the S-phase cell fraction, autoradiographically determined as thymidine labeling index (TLI), were investigated within a prospective randomized phase III clinical trial on squamous-cell carcinoma of the oral cavity, including surgery or primary chemotherapy (PCT), which foresaw the prospective determination of biological markers. Pathological response was defined as the achievement after PCT of a pathological complete remission or the presence of microresidual disease. The study was performed on tumors obtained from a series of 100 previously untreated patients with resectable T2-4N0-2M0 carcinoma. All biomarkers were unrelated, except for an inverse relation between TLI and GST-pi and a direct relation between bcl-2 and bax expression. In patients treated with surgery alone, 3-year disease-free survival (DFS) appeared to be weakly, but not significantly, related only to GST-pi and p53 expression. In patients treated with PCT, pathological response and DFS were independent of p53 expression and cell proliferation. Conversely, low GST-pi and bax expression were indicative of pathological response but lost relevance as predictors of DFS, whereas absence of bcl-2 was associated with high probability of 3-year DFS in the overall series as well as in non-responding patients. Within this latter sub-set, all patients with bcl-2-positive tumors relapsed within 1 year of surgery, whereas a 60% probability of 3-year DFS was observed for patients with bcl-2-negative tumors (p = 0.02). This interim analysis appears to indicate that some biofunctional markers can provide information on pathological response to PCT and could help in understanding treatment efficacy at a cellular level.

ABSTRACT: Cisplatin is an active drug in head and neck cancer. Paclitaxel seems a promising drug. This article reports a phase II assessment of the combination of the two.
Twenty-three patients were treated with paclitaxel 90 mg/m2 over three hours plus cisplatin 60 mg/m2 every other week. Sixteen patients had locoregional disease and seven had metastatic disease. None of the patients had previously been treated with chemotherapy. Nine patients had had radiotherapy to the target lesions.
One patient was not evaluable for response. Partial responses were observed in 32% of evaluable patients. Toxicity included asthenia (56%), neutropenia, peripheral neuropathy, anemia and vomiting.
The overall response rate observed in this study does not seem to justify the use of this chemotherapy regimen in the palliative setting.

ABSTRACT: To evaluate the activity of CAP regimen in advanced salivary gland carcinomas.
Twenty-two patients with advanced salivary gland carcinomas were treated according to the CAP regimen. All patients were previously treated with surgery and/or radiotherapy and/or chemotherapy. Seven patients had local or locoregional disease, nine patients had local and metastatic disease, six patients had metastatic disease only. The most common histologies were included.
Of 22 patients, six achieved a partial response (27%, 95% CI: 11%-50%): no complete response was observed. Response duration ranged between 3 and 13 months (median seven months). The median survival time for the entire series was 21 months.
In this investigation, on 22 consecutive patients, CAP combination provided an overall response rate of 27%. This study confirms that, at present, available drugs yield poor results, either as single agents or as combination therapy.

ABSTRACT: The current treatment options for cancer of the base of the tongue and glosso-epiglottic region are surgery, radiotherapy, or a combination of both modalities. Comparisons between different modalities are not common in the literature, and a real standard of treatment has not yet been established. The purpose of our study was to evaluate the results of treatment in a large series of patients from 18 Italian institutions in relation to the main treatment adopted.
The present study is a retrospective survey. The series was divided into a combined surgery group and a radiotherapy group. The Kaplan-Meier method and the log-rank test were used for survival calculations and comparisons.
Eight hundred patients were registered (25.7% stage III and 62% stage IV), 336 in the surgery and 372 in the radiotherapy group. Conventional fractionation was adopted in almost all cases. The five-year overall and disease free survival of the whole series was 32% and 38%, respectively. Survival was slightly better for patients with tumors of the glosso-epiglottic region than for those with a tumor of the base of the tongue. Five-year disease-free survival was 55% for patients treated with surgery +/- radiochemotherapy and 26% for those submitted to radiotherapy alone or in combination with chemotherapy. As far as the total dose and the treatment duration were concerned, only 26% of the patients of the radiotherapy group met the established criteria of adequacy, but in patients with adequate radiation the control rate was better only for small tumors (T1-T2).
The results in patients treated with surgery +/- postoperative radiotherapy were similar to or better than those reported in the best series in the literature. By contrast, the survival rate of irradiated patients was lower than those reported by other centers.
