Comparison of concurrent chemoradiation therapy with weekly cisplatin versus monthly fluorouracil plus cisplatin in FIGO stage IIB-IVA cervical cancer

Objective

Concurrent chemoradiation therapy (CCRT) is the standard treatment for locally advanced cervical cancer. Although the optimal chemotherapeutic regimen is not yet defined, previous randomized trials have demonstrated that 5-fluorouracil (5-FU) plus cisplatin every 3 weeks and weekly cisplatin are the most popular regimens. The purpose of this study was to compare the outcomes of weekly CCRT with cisplatin and monthly CCRT with 5-FU plus cisplatin for locally advanced cervical cancer.

Methods

We retrospectively reviewed data from 255 patients with FIGO stage IIB-IVA cervical cancer. Patients were classified into two CCRT groups according to the concurrent chemotherapy: weekly CCRT group, consisted of CCRT with weekly cisplatin for six cycles; and monthly CCRT group, consisted of CCRT with cisplatin and 5-FU every 4 weeks for two cycles followed by additional consolidation chemotherapy for two cycles with the same regimen.

Results

Of 255 patients, 152 (59.6%) patients received weekly CCRT and 103 (40.4%) received monthly CCRT. The mean follow-up period was 39 months (range, 1 to 186 months). Planned CCRT was given to 130 (85.5%) patients in weekly CCRT group and 84 (81.6%) patients in monthly CCRT group, respectively. Severe adverse effects were more common in the monthly CCRT group than in the weekly CCRT group. There were no statistically significant differences in progression-free survival and overall survival between the two groups (p=0.715 and p=0.237).

Conclusion

Both weekly CCRT and monthly CCRT seem to have similar efficacy for patients with locally advanced cervical cancer, but the weekly cisplatin is better tolerated.

TPF sequential therapy: when and for whom?

Concurrent chemoradiation is a standard approach for the treatment of locally advanced squamous cell carcinoma of the head and neck. However, sequentially administered chemotherapy and radiotherapy/chemoradiation may be an effective alternative for some patients. Although chemoradiation is a highly effective treatment approach, it is associated with high incidences of severe acute toxicities, including mucositis. In addition, late toxicities can cause long-term morbidity in a substantial proportion of patients. In a retrospective analysis of three Radiation Therapy Oncology Group trials, pharyngeal dysfunction was seen in 27% of patients and feeding tube dependence and laryngeal dysfunction were each seen in approximately 12% of patients. Sequential administration of chemotherapy and radiotherapy, with a doublet cisplatin and 5-fluorouracil (PF) induction chemotherapy regimen, is associated with less acute severe mucositis than concomitantly administered cisplatin and radiotherapy. The addition of the taxane docetaxel to PF has resulted in the highly active triplet induction regimen TPF. Data from randomized trials indicate that TPF sequential therapy may be an effective alternative to concurrent chemoradiation for some patients. TPF is well tolerated, although it is associated with a higher incidence of hematologic adverse events than with PF, including neutropenia and neutropenia-related complications. This may be managed by the use of prophylactic G-CSF and/or antibiotics. Patients suitable for treatment with a TPF-based sequential administration approach include those with a good performance status, no contraindication to cisplatin or taxanes, and locally advanced oropharyngeal, hypopharyngeal, or laryngeal cancer with a high tumor load.     

Toxicity profile and clinical outcomes in locally advanced head and neck cancer patients treated with induction chemotherapy prior to concurrent chemoradiation

The use of induction chemotherapy prior to chemoradiation for locally advanced head and neck squamous cell carcinoma (LA-HNSCC) remains controversial. We explored whether toxicity from induction chemotherapy influenced the delivery of concurrent chemoradiation. Among 171 consecutive previously unirradiated patients with HNSCC treated with combined chemotherapy and radiation, we identified 66 patients with stage III-IVB head and neck carcinoma who were treated with induction chemotherapy prior to planned chemoradiation. The most common induction regimen was docetaxel, cisplatin and 5-FU (TPF; 80%) for 2 to 3 cycles. Mean radiation dose was 72 Gy (range, 36-75 Gy). Concurrent chemotherapy regimens included cisplatin (26%), cetuximab (5%) and 5-fluorouracil/hydroxyurea (65%)-based regimens. At a median follow-up of 27 months (range, 9-56 months), the 2-year locoregional control and distant control rates were 85 and 86%, respectively. The 2-year disease-free survival and overall survival rates were 74 and 80%, respectively. Although there were no grade 5 toxicities during induction chemotherapy, 26% of patients required hospitalization for adverse events, including 5% needing intensive care. The most common high grade adverse events were grade 4 neutropenia (21%) and neutropenic fever (17%). Six percent of patients were unable to tolerate concurrent chemotherapy. The 2-year disease-free survival was significantly higher in patients able to complete induction and concurrent chemoradiation as planned (83 vs. 27%, p<0.001). Induction chemotherapy followed by concurrent chemoradiation results in promising survival rates in our cohort of advanced head and neck carcinoma patients. Due to severe toxicities in a subset of patients, this strategy is only recommended in selected high-risk patients who are carefully followed by an experienced multidisciplinary team.

Randomized trial of weekly docetaxel and cisplatin combined with concurrent 3DCRT in patients with locally advanced esophageal cancer

Objective

This randomized controlled clinical study was to assess and compare the efficacy and safety of two chemoradiotherapy regimens [cisplatin + 5-fluorouracil + 3 dimensional conformal radiation therapy (3DCRT) and cisplatin + weekly docetaxel + 3DCRT] in patients with locally advanced esophageal squamous cell carcinoma.

Methods

A total of seventy-four patients with clinical stages IIB to IIIB esophageal squamous cell carcinoma were enrolled. Chemotherapy for PF group comprised 5-fluorouracil at days 1–5 (250 mg/m²/d) and cisplatin (20 mg/m²) at days 1–3 of every 28-day cycle; full treatment course included 2 cycles. Chemotherapy for DP group comprised docetaxel (20 mg/m²) and cisplatin (20 mg/m²) at days 1, 8, 15, 22, 29, and 36. Both groups treated with concurrent 60 Gy 3DCRT at 200 cGy/d.

Results

Seventy-four patients were enrolled and 71 completed the planned treatment, with a follow-up rate of 95.94%. Short-term curative effect was not statistically significant between the two groups (P = 0.471). The 2-year survival rates were 65.7% and 61.1%, respectively (P = 0.806), 5 years survival rates were 34.29% and 27.78%, respectively (P = 0.221), and there was no significant difference by Fisher test (P = 0.734). As common side effects, incidence rates of radioactive esophagitis and hematological toxicity were lower in DP group.

Conclusion

For locally advanced esophageal cancer patients, current chemoradiotherapy with chemotherapy regimen of weekly docetaxel plus cisplatin has equal curative effect with 5-fluorouracil plus cisplatin, but well-tolerated by reducing side effects such as radioactive esophagitis and bone marrow suppression.
