Clinical predictive factors of pathologic complete response in locally advanced rectal cancer

Background Predictive factors of pathologic complete response (pCR) after neoadjuvant chemoradiotherapy (nCRT) in locally advanced rectal cancer (LARC) are still not identified. The purpose of this study was to define them. Materials and Methods Data from consecutive LARC patients treated between January 2008 and June 2014 at our Institution were included in the analysis. All patients were treated with a long course of nCRT. Demographics, initial diagnosis and tumor extension details, as well as treatment modalities characteristics were included in the univariate and logistic regression analysis. Results In total 99 patients received nCRT, of whom 23 patients (23.2%) achieved pCR. Patients with and without pCR were similar in term of age, sex, comobidities, BMI and tumor characteristics. Multivariate logistic regression indicated that pre-treatment tumor size ≤ 5 cm was a significant predictor for pCR (p = 0.035), whereas clinical N stage only showed a positive trend (p = 0.084). Conclusions Tumor size at diagnosis could be used to predict pCR, and thus to individualize therapy in LARC patients management. Validation in other studies is needed.

Relationship of Clinical and Pathologic Nodal Staging in Locally Advanced Breast Cancer: Current Controversies in Daily Practice?

Systemic neo-adjuvant therapy plays a primary role in the management of locally advanced breast cancer. Without having any negative effect in overall survival, induction chemotherapy potentially assures a surgery approach in unresectable disease or a conservative treatment in technically resectable disease and acts on a well-vascularized tumor bed, without the modifications induced by surgery. A specific issue has a central function in the neo-adjuvant setting: lymph nodes status. It still represents one of the strongest predictors of long-term prognosis in breast cancer. The discussion of regional radiation therapy should be a matter of debate, especially in a pathological complete response. Currently, the indication for radiotherapy is based on the clinical stage before the surgery, even for the irradiation of the loco-regional lymph nodes. Regardless of pathological down-staging, radiation therapy is accepted as standard adjuvant treatment in locally advanced breast cancer.

Irradiated fields spared Stevens-Johnson syndrome in a patient undergoing radiotherapy for bone metastases

Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are two of the most severe, rare, and life-threatening adverse reactions to medications. Their incidence is approximately two patients per million population per year. Several cases have been reported in the literature in which SJS and TEN have occurred in patients with a neoplasm undergoing radiation therapy and who are taking an anticonvulsant. We report a case of SJS-TEN that developed in a 51-year-old woman with nonresectable non-small-cell lung cancer during treatment with phenobarbital plus radiation therapy for bone metastases but in whom the irradiated areas did not exhibit the SJS skin reaction. To our knowledge, no similar cases have been reported in the literature.

Follow-up program in head and neck cancer

Follow-up program in head and neck cancer (HNC) is an important issue in patients management. It represents the major dilemma in daily practice clinic. Many guidelines have been published in order to better define the best clinical protocol, but a consensus has not been attained yet. We constructed a follow-up program based on specific primary subsite, to standardize patients surveillance after treatment of HNC.

Primary thyroid angiosarcoma: A systematic review

Thyroid angiosarcoma (TAS) is rare and represents a very aggressive malignancy. Its rarity is principally linked to two major pitfalls. Firstly, TAS histopathology diagnosis can be difficult; second, the limited clinical experience with this condition can make its management complex. We conducted a detailed systematic review, focusing on the knowledge available regarding TAS etiopathogenesis, treatment options and prognosis. The aim is to present the main TAS characteristics and to summarize the clinical experiences described worldwide, in order to provide a useful clinical tool.

Management of salivary gland malignant tumor: the Policlinico Umberto I, “Sapienza” University of Rome Head and Neck Unit clinical recommendations

Salivary gland malignant tumor (SGMT) is a malignant disease requiring multidisciplinary approach. The rare incidence and the consequent lack of robust evidence-based medicine has called for a comprehensive update to draw recommendations for clinical practice. This paper is a summary of the XXX Head and Neck Unit guidelines regarding the management of SGMT. Recommendations include the indications for exclusive and adjuvant therapy, as well as metastatic management, for both major and minor SGMT.

Solitary rib metastasis of nasopharyngeal carcinoma.

We report a case of a 49-year-old man who developed solitary rib metastasis of nasopharyngeal cancer. Patient had been treated for primary carcinoma with radiation therapy and concomitant chemotherapy. The bone metastasis presented as bulky, solid, painful mass in the posterior arch of 10th rib, within nine months the end of treatment. Biopsy of the solitary lesion presented the same histological characteristics as those of primary lesion. Although there are reported in literature series of nasopharyngeal cancer metastasizing to bone, we did not find previously published report of a nasopharyngeal carcinoma metastasizing only to a rib.

Cetuximab and Oral Mucositis: Is it Different from Oral Mucositis Caused by Other Drugs?

Purpose: To estimate frequency of oral mucositis in treatment for head and neck cancer with radiotherapy and concurrent cetuximab and to determine whether it has different characteristics from mucositis caused by other drugs. Materials and methods: Subjects with locally advanced, primary non-metastatic, squamous cell carcinoma located in the oropharynx were treated with radiation therapy plus concomitant cetuximab. Results: None of patients received their full planned course of combination treatment due to excessive mucosal toxicity. All patients developed oral mucositis within about 10-15 days: it began directly, without escalation, as grade ≥ 3; it was associated with severe pain and trismus; it was never associated to specific supra-infections; the evolution and the consequent resolution of clinical discomfort required several days and the treatment with corticosteroids did not represent the solution formula. Conclusion: Cetuximab induced oral mucositis have the following specific characteristics: time of onset, mode of clinical expression, severity, association with trismus and minimal response to corticosteroid therapy. Considering that the majority of studies do not reveal oral toxicity associated with cetuximab, future clinical trials should focus on specific topics to improve the definition of documented oral toxic effects.

Induction chemotherapy followed by neoadjuvant chemoradiotherapy and surgery in locally advanced rectal cancer: preliminary results of a phase II study

Background and purpose To report preliminary results of induction chemotherapy (IC) followed by neoadjuvant chemoradiotherapy (CRT) and surgery in locally advanced rectal cancer (LARC) patients. Materials and methods This is the preliminary evaluation of a phase II study. Patients with histologically proven rectal adenocarcinoma, stage II-III disease, who met the inclusion criteria, received induction FOLFOXIRI (5-FU, leucovorin, oxaliplatin and irinotecan) regimen in combination with targeted agents followed by CRT and surgery. Analysis of the first 8 patients was required to confirm the treatment feasibility before the accrual of 20 additional patients. Results The first 8 patients were evaluated. The median follow-up time was 23 months. There were no treatment-related deaths. Trimodality strategy was well tolerated with high compliance and a good level of toxicity. There were no evidence of febrile neutropenia and any grade 4 adverse events were recorded. Three patients had pathologic complete response (pCR) and 1 patient had a nearly pCR (ypT1 ypN0). Conclusion Preliminary results are encouraging. FOLFOXIRI regimen plus targeted agents followed by CRT and surgery seems a safe approach. Longer follow-up and higher number of patients are mandatory to confirm such findings.

The role of different adjuvant therapies in locally advanced gastric adenocarcinoma

Background and Purpose Complete surgical resection remains the only curative treatment option in locally advanced gastric cancer (GC). Several studies were conducted to prevent local recurrence and to increase the chance of cure. The aim of this study was to summarize our experience in locally advanced GC patients treated with adjuvant chemoradiotherapy (CRT) and to evaluate overall survival (OS), disease-free survival (DFS), toxicity rate and compliance to treatment. Materials and Methods Locally advanced GC stage IB-III were included. Adjuvant CRT consisted of 45–50.4 Gy (1.8 Gy/day, 5 days/week) with concomitant Macdonald regimen (Mcd) or Epirubicin, Cisplatin and 5-Fluorouracil (ECF) scheme. Univariate and multivariate analysis of several prognostic factors for OS was conducted. Results Fourty-nine GC patients were treated: 24 received Mcd and 25 received ECF. Median follow up was 48 months. Acute grade 3–4 toxicity was observed in 6 patients. The 2-year and 5-year OS rates were 65.3% and 41.5%, respectively. The 2-year and 5-year DFS were 59.2% and 41.2%, respectively. No prognostic factors were significantly associated with OS. Conclusions Adjuvant CRT is a feasible strategy in locally advanced GC. It has an acceptable toxicity rate and it is able to increase both DFS and OS.
