Sequential chemotherapy regimen of induction with panitumumab and paclitaxel followed by radiotherapy and panitumumab in patients with locally advanced head and neck cancer unfit for platinum derivatives. The phase II, PANTERA/TTCC-2010-06 study.

Clin Transl Oncol 2021 Apr 19. Epub 2021 Apr 19.

Medical Oncology Service, Institut Català D'Oncologia (ICO) Hospitalet, Barcelona, Spain.

Background: Sequential treatment of Panitumumab (Pb) plus Paclitaxel (Px) as induction treatment (IT) followed by concurrent bioradiotherapy (Bio-RT) with Pb may be an alternative for locally advanced squamous cell carcinoma of the head and neck (LA-SCCHN) in patients ineligible for high-dose cisplatin therapy.

Methods: Phase II, single-arm, multicentre study, with two-stage design, in patients ≥ 18 years with stage III-IVa-b LA-SCCHN unfit for platinum. Patients received Px + Pb (9 weeks) as IT followed by Bio-RT + Pb. Primary endpoint: overall response rate (ORR) after IT, defined as: more than 70% of patients achieving complete response (CR) or partial response (PR) to IT. Secondary end-points: progression-free survival, organ preservation rate, safety profile.

Results: Study ended prematurely (51 patients) due to slow recruitment. ORR: 66.7% (95% CI: 53.7-79.6), 8 (15.7%) CR and 26 (51.0%) PR. 39 patients (76%) completed radiotherapy (RT). Pb and/or Px-related adverse events (AEs) grade 3-4: 56.9% during IT and 63.4% during the concomitant phase, of which most common were skin toxicity (33.3%). Five deaths occurred during treatment, two of them (3.9%) were Pb and/or Px-related.

Conclusions: Although underpowered, ORR was higher than the pre-specified boundary for considering the treatment active. Although Px + Pb as IT provides some benefit, the safety profile is worse than expected. To consider Pb + Px as IT as an alternative for platinum-unsuitable LA-SCCHN, further research/investigation would be needed.

Incidence of chemotherapy-induced nausea and vomiting with moderately emetogenic chemotherapy: ADVICE (Actual Data of Vomiting Incidence by Chemotherapy Evaluation) study.

Support Care Cancer 2015 Sep 17;23(9):2833-40. Epub 2015 Jun 17.

Servicio de Oncología Médica, Hospital General Universitario Gregorio Marañón, C/ Dr. Esquerdo 46, 28007, Madrid, Spain.

Purpose: This study aims to determine the incidence of nausea and vomiting (CINV) after moderately emetogenic chemotherapy (MEC), under medical practice conditions and the accuracy with which physicians perceive CINV.

Methods: Chemotherapy-naive patients receiving MEC between April 2012 and May 2013 were included. Patients completed a diary of the intensity of nausea and number of vomiting episodes. Complete response and complete protection were assessed as secondary endpoints.

Results: Of 261 patients included, 240 were evaluated. Median age was 64 years, 44.2 % were female and 11.2 % were aged less than 50 years; 95.3 % of patients received a combination of 5-hydroxytryptamine 3 (5-HT3) antagonist + corticosteroid as antiemetic treatment. Vomiting within 5 days of chemotherapy administration occurred in 20.8 %, nausea in 42 % and significant nausea in 23.8 % of patients. An increase in the percentage of patients with significant nausea (from 9.4 to 21.7 %) and vomiting (from 9.2 to 16.5 %) was observed from the acute to the delayed phase. Complete response was 84.2 % in the acute phase, 77 % in the late phase and 68.9 % in overall period. Complete protection was 79.5 % in the acute phase, 68.8 % in the late phase and 62.4 % throughout the study period. Physicians estimated prophylaxis would be effective for 75 % of patients receiving MEC, compared with 54.1 % obtained from patients' diary.

Conclusion: Despite receiving prophylactic treatment, 31 % of patients did not achieve a complete response and 38 % complete protection. In general, nausea was worse controlled than vomiting. The results also showed the late phase was worse controlled than the acute phase in all variables. Healthcare providers overestimated the effectiveness of antiemetic prophylaxis.

Phase II study of capecitabine as palliative treatment for patients with recurrent and metastatic squamous head and neck cancer after previous platinum-based treatment.

Br J Cancer 2010 Jun 18;102(12):1687-91. Epub 2010 May 18.

Medical Oncology Department of University Hospital Miguel Servet Hospital, Paseo de Isabel La Católica 1-3, 50009 Zaragoza, Spain.

Background: Platinum-based therapy (PBT) is the standard therapy for recurrent and/or metastatic head and neck cancer (HNC), but the incidence of recurrence remains high. This study evaluates the efficacy and tolerability of capecitabine as palliative monotherapy for recurrent HNC previously treated with PBT.

Methods: Patients aged 18-75 years, with Eastern Cooperative Oncology Group performance status 0-2, squamous HNC with locoregional and/or metastatic recurrence previously treated with PBT and adequate organ functions, were included. Capecitabine (1.250 mg m(-2) BID) was administered on days 1-14 every 21 days for at least two cycles.

Results: A total of 40 male patients with a median age of 58 years were analysed. All patients received a median number of four cycles of capecitabine (range: 1-9) and the median relative dose intensity was 91%. Seven patients were not evaluable for response. Overall response rate was 24.2%. Median time to progression and overall survival were 4.8 and 7.3 months, respectively. Haematological adverse events (AEs) grade 3/4 were reported in six patients. Most common grade 3/4 non-haematological AEs were asthenia (12.5%), palmar-plantar eritrodisestesia (10%), mucositis (10%), dysphagia (10%) and diarrhoea (7.5%).

Conclusions: Capecitabine seems to be an active, feasible and well-tolerated mode of palliative treatment for advanced HNC patients who have previously received PBT schedules.

Evaluation of multiparameter flow cytometry for the detection of breast cancer tumor cells in blood samples.

Am J Clin Pathol 2005 Jan;123(1):66-74

Cytometry Service, University of Salamanca, Spain.

We comparatively evaluated different cytokeratin (CK) reagents analyzed by flow cytometry (FCM) for the identification of the best combination of DNA/CK staining for detecting minimal numbers of breast cancer cells in peripheral blood (PB). In 59 primary breast cancer tumors, we comparatively analyzed the reactivity for up to 6 different anti-CK reagents using multiparameter FCM: anti-CK7, anti-CK20, anti-pan-CK, anti-CK8/CK18, anti-CK8, and anti-CK18. Afterward, dilutional experiments of Michigan Cancer Foundation (MCF)7 breast cancer cells in PB were performed, and the sensitivity of a DNA/CK18 staining was evaluated. Our results showed that anti-CK18 reagents were those providing the brightest and more sensitive staining for primary breast cancer tumor cells by FCM. Dilutional experiments of MCF cells in PB showed that the DNA/anti-CK18 double staining was highly specific for the identification of epithelial cells; its sensitivity ranged between 10(-6) and 10(-7) (detection of 1 tumor cell among 10(6) to 10(7) nucleated blood cells). Combined assessment of DNA cell contents and reactivity for CK18 by FCM is a sensitive method for the specific identification of breast cancer cells in PB.
