Clinicobiological progression and prognosis of oral squamous cell carcinoma in relation to the tumor invasive front: impact on prognosis.

CONCLUSION: There are several factors that influence the final outcome when treating oral squamous cell carcinoma (OSCC). Invasive front phenomena and more importantly their clinicopathological translation can have a direct impact on survival, and subsequently on the decision for an adjuvant treatment. OBJECTIVES: In recent years, the concept of tumor-host interaction has been the subject of substantial efforts in cancer research. Tumoral behavior may be better understood when studying the changes occurring at the tumor-host interface. This study evaluated the influence of several clinicopathological features on the outcome of OSCCs. METHODS: The clinical records and pathology specimens of 54 patients with OSCC treated by primary resection were reviewed retrospectively. The pathologic features reviewed were: invasive front grading (IFG), stromal reaction, lymphovascular invasion (LVI), perineural invasion (PNI), margin status, and depth of invasion. RESULTS: High IFGs had a significant relationship with pT status and pN status. High IFGs were strongly correlated with nodal metastases (odds ratio (OR) = 4.77; confidence interaval (CI) = 1.37-16.64). Concerning survival, IFG had a strong impact on disease-free survival in patients treated unimodally, as did the depth of invasion in the same group. Lymphovascular involvement was found to have a negative impact on overall survival in patients treated multimodally.

Prognostic value of arginase-II expression and regulatory T-cell infiltration in head and neck squamous cell carcinoma.

Tumor-infiltrating lymphocytes are present in a variety of tumors and play a central role in antitumor immune responses. Nevertheless, most cancers progress probably because tumors are only weakly immunogenic and develop multiple immunosuppressive mechanisms. In the present study, on head and neck squamous cell carcinoma, we found high intraepithelial infiltration of regulatory FOXP3(+) T cells, and relatively high levels of BDCA2(+) and FOXP3(+) cells in stromal (peripheral) regions of the tumors. Tumor-infiltrating (intraepithelial) FOXP3(+) T cells were significantly more frequent in patients with oropharynx and oral cavity squamous cell carcinoma and in patients without lymph node metastasis. Furthermore, arginase-II (ARG2) was expressed by 60%, inducible nitric oxide synthetase by 9%, cyclooxygenase-2 by 43%, and B-cell lymphoma 2 (BCL2) by 26% of tumors. Interestingly, the absence of ARG2 expression, enhanced stromal infiltration of CD11c(+) myeloid dendritic cells, and high numbers of FOXP3(+) T cells were each significantly associated with prolonged overall survival, and the latter two parameters were also confirmed by multivariate analysis. For disease-free survival, multivariate analysis revealed significant negative correlations with BCL2 and ARG2 expression by tumor cells. These findings shed new light on mechanisms of cancer progression, and provide rationales for therapeutic inhibition of immunosuppressive mechanisms in head and neck squamous cell carcinoma.

MAGE-A3 and MAGE-A4 specific CD4(+) T cells in head and neck cancer patients: detection of naturally acquired responses and identification of new epitopes.

Frequent expression of cancer testis antigens (CTA) has been consistently observed in head and neck squamous cell carcinomas (HNSCC). For instance, in 52 HNSCC patients, MAGE-A3 and -A4 CTA were expressed in over 75% of tumors, regardless of the sites of primary tumors such as oral cavity or hypopharynx. Yet, T-cell responses against these CTA in tumor-bearing patients have not been investigated in detail. In this study, we assessed the naturally acquired T-cell response against MAGE-A3 and -A4 in nonvaccinated HNSCC patients. Autologous antigen-presenting cells pulsed with overlapping peptide pools were used to detect and isolate MAGE-A3 and MAGE-A4 specific CD4(+) T cells from healthy donors and seven head and neck cancer patients. CD4(+) T-cell clones were characterized by cytokine secretion. We could detect and isolate MAGE-A3 and MAGE-A4 specific CD4(+) T cells from 7/7 cancer patients analyzed. Moreover, we identified six previously described and three new epitopes for MAGE-A3. Among them, the MAGE-A3(111-125) and MAGE-A3(161-175) epitopes were shown to be naturally processed and presented by DC in association with HLA-DP and DR, respectively. All of the detected MAGE-A4 responses were specific for new helper epitopes. These data suggest that naturally acquired CD4(+) T-cell responses against CT antigens often occur in vivo in HNSCC cancer patients and provide a rationale for the development of active immunotherapeutic approaches in this type of tumor.

Pattern and clinical significance of cancer-testis gene expression in head and neck squamous cell carcinoma.

Cancer-testis (CT) antigens comprise families of tumor-associated antigens that are immunogenic in patients with various cancers. Their restricted expression makes them attractive targets for immunotherapy. The aim of this study was to determine the expression of several CT genes and evaluate their prognostic value in head and neck squamous cell carcinoma (HNSCC). The pattern and level of expression of 12 CT genes (MAGE-A1, MAGE-A3, MAGE-A4, MAGE-A10, MAGE-C2, NY-ESO-1, LAGE-1, SSX-2, SSX-4, BAGE, GAGE-1/2, GAGE-3/4) and the tumor-associated antigen encoding genes PRAME, HERV-K-MEL, and NA-17A were evaluated by RT-PCR in a panel of 57 primary HNSCC. Over 80% of the tumors expressed at least 1 CT gene. Coexpression of three or more genes was detected in 59% of the patients. MAGE-A4 (60%), MAGE-A3 (51%), PRAME (49%) and HERV-K-MEL (42%) were the most frequently expressed genes. Overall, the pattern of expression of CT genes indicated a coordinate regulation; however there was no correlation between expression of MAGE-A3/A4 and BORIS, a gene whose product has been implicated in CT gene activation. The presence of MAGE-A and NY-ESO-1 proteins was verified by immunohistochemistry. Analysis of the correlation between mRNA expression of CT genes with clinico-pathological characteristics and clinical outcome revealed that patients with tumors positive for MAGE-A4 or multiple CT gene expression had a poorer overall survival. Furthermore, MAGE-A4 mRNA positivity was prognostic of poor outcome independent of clinical parameters. These findings indicate that expression of CT genes is associated with a more malignant phenotype and suggest their usefulness as prognostic markers in HNSCC.

Mixed medullary-papillary carcinoma of the thyroid: report of a case and review of the literature.

BACKGROUND: Mixed medullary-follicular thyroid carcinoma denotes a rare and heterogeneous group of tumors displaying morphological and immunophenotypical features of both origins within the same lesion. METHOD: We report a case of a 41-year-old woman with a lump in the right side of the neck, increasing in pain and size over several weeks. Serum levels of calcitonine (1140 ng/L) and carcinoembryonic antigen (288 microg/L) were very high. Fine-needle aspiration cytology suggested a diagnosis of medullary thyroid carcinoma. Total thyroidectomy, along with bilateral functional neck and mediastinal lymph-node dissection, were performed. RESULTS: The histopathological examination yielded a diagnosis of medullary carcinoma in the right thyroid lobe, closely intermingled with a nonencapsulated classical papillary carcinoma. One ipsilateral lymph node showed micrometastasis of the medullary counterpart. CONCLUSION: When compared with other cases reported in literature, this particular presentation should be recognized, if required, morphologic and functional criteria are used. The treatment is mostly surgical, driven by the medullary component. The presence of micrometastasis in 1 ipsilateral cervical lymph-node underlines the importance of cervicomediastinal lymph-node dissection and careful searching for metastatic disease.

Feasibility and efficacy of accelerated weekly concomitant boost postoperative radiation therapy combined with concomitant chemotherapy in patients with locally advanced head and neck cancer.

BACKGROUND: The aim of this study was to assess feasibility and efficacy of weekly concomitant boost accelerated postoperative radiation therapy (PORT) with concomitant chemotherapy (CT) in patients with locally advanced head and neck cancer (LAHNC). METHODS AND MATERIALS: Conformal or intensity-modulated 66-Gy RT was performed in 5.5 weeks in 40 patients. Cisplatin was given at days 1, 22, and 43. Median follow-up was 36 months. RESULTS AND DISCUSSION: Grade 3 mucositis, dysphagia, and erythema was observed in ten (25%), nine (23%), and six (13%) patients, respectively. Grade 3 or more anemia was observed in two (6%) patients, and leukopenia in five (13%) patients. No grade 3 or 4 thrombocytopenia was observed. Grade 3 nephrotoxicity was observed in one patient (3%). No treatment-related mortality was observed. Grade 2 or more xerostomia and edema were observed in ten (25%) and one (3%) patient, respectively. Locoregional relapse occurred in eight patients, and seven patients developed distant metastases. Median time to locoregional relapse was 6 months. Three-year overall, disease-free survival, and locoregional control rates were 63%, 62%, and 81%, respectively. Multivariate analysis revealed that the only prognostic factor was nodal status. CONCLUSION: Reducing overall treatment time using accelerated PORT/CT by weekly concomitant boost (six fractions per week) combined with concomitant cisplatin CT is easily feasible with acceptable morbidity.

Decrease in hemoglobin levels following surgery influences the outcome in head and neck cancer patients treated with accelerated postoperative radiotherapy.

AIM: To assess the influence of hemoglobin (Hb) levels in locally advanced head and neck cancer (LAHNC) patients treated with surgery and postoperative radiotherapy (PORT). MATERIAL AND METHODS: Pre- and postoperative Hb levels were collected in 79 patients treated with surgery followed by accelerated PORT for LAHNC. Median follow-up was 52 months (range 12-95 months). RESULTS AND DISCUSSION: Four-year overall survival (OS) rate was 51%. Neither pre- nor postoperative Hb level (<120 or 130 g/l in women or men, respectively) influenced the outcome. However, when Hb decrease between pre- and postoperative Hb values was taken into account, 4-year OS was significantly higher in patients with Hb difference less than 38 g/l (quartile value) compared with those with Hb decrease 38 g/l or more (61% versus 16%, P = 0.008). CONCLUSION: Decrease in Hb level by more than 38 g/l after surgery secondary to blood loss influences the outcome when postoperative RT is indicated.

[Immunotherapy: a new alternative treatment for head and neck squamous cell carcinoma]. / Immunothérapie: une solution dans les carcinomes épidermoïdes de la sphère ORL.

In the past decades, prognosis of head and neck squamous cell carcinoma (HNSCC) has not improved even though treatment has made substantial progress. Since the description of immune response against some cancers, antitumoral immunotherapy has been studied to be used as adjunctive treatment in various cancer types. This article review contributions made in the field of immunotherapy on HNSCC in the past few years. It appears that this approach may play an important role in the treatment of head and neck squamous cell carcinoma. Among various TAAs, cancer testis antigens family may be promising candidates for specific immune therapy in HNSCC. Ongoing studies will confirm whether expression CTAs generate an immune response in clinical vaccine trials.

Feasibility and efficacy of subcutaneous amifostine therapy in patients with head and neck cancer treated with curative accelerated concomitant-boost radiation therapy.

OBJECTIVE: To assess the feasibility and efficacy of subcutaneous amifostine therapy in patients with head and neck cancer treated with curative accelerated radiotherapy (RT). DESIGN: Retrospective study. SETTING: University of Lausanne, Lausanne, Switzerland. PATIENTS: Thirty-three consecutive patients (male-female ratio, 4.5; median age, 54 years [age range, 39-76 years]). INTERVENTIONS: Between November 2000 and January 2003, the 33 patients were treated with curative definitive (n = 19) or postoperative (n = 14) RT with (n = 26) or without (n = 7) chemotherapy. All patients received conformal RT. Fractionation schedule consisted of concomitant-boost (Friday afternoon session) accelerated RT using 70 Gy (2 Gy per fraction) in 6 weeks in patients treated with definitive RT and 66 Gy (2 Gy per fraction) in 5 weeks and 3 days in the postoperative setting. Parotid glands received at least 50 Gy in all patients. Amifostine was administered to a total dose of 500 mg subcutaneously, 15 to 30 minutes before morning RT sessions. RESULTS: All patients received their planned treatment (including chemotherapy). Ten patients received the full schedule of amifostine (at least 25 injections), 9 received 20 to 24 doses, 4 received 10 to 19 doses, 5 received 5 to 9 doses, and 5 received fewer than 5 doses. Fifteen patients (45%) did not show any intolerance related to amifostine use. Amifostine therapy was discontinued because of nausea in 11 patients (33%) and hypotension in 6 patients (18%), and 1 patient refused treatment. No grade 3, amifostine-related, cutaneous toxic effects were observed. Radiotherapy-induced grade 3 acute toxic effects included mucositis in 14 patients (42%), erythema in 14 patients (42%), and dysphagia in 13 patients (39%). Late toxic effects included grade 2 or more xerostomia in 17 patients (51%) and fibrosis in 3 patients (9%). Grade 2 or more xerostomia was observed in 8 (42%) of 19 patients receiving 20 injections or more vs 9 (64%) of 14 patients receiving fewer than 20 injections (P = .15). CONCLUSIONS: Subcutaneous amifostine administration in combination with accelerated concomitant-boost RT with or without chemotherapy is feasible. The major adverse effect of subcutaneous administration was nausea despite prophylactic antiemetic medication, and hypotension was observed in only 6 patients (18%).

Decreased local control following radiation therapy alone in early-stage glottic carcinoma with anterior commissure extension.

PURPOSE: To assess the patterns of failure in the treatment of early-stage squamous cell carcinoma of the glottic larynx. PATIENTS AND METHODS: Between 1983-2000, 122 consecutive patients treated for early laryngeal cancer (UICC T1N0 and T2N0) by radical radiation therapy (RT) were retrospectively studied. Male-to-female ratio was 106 : 16, and median age 62 years (35-92 years). There were 68 patients with T1a, 18 with T1b, and 36 with T2 tumors. Diagnosis was made by biopsy in 104 patients, and by laser vaporization or stripping in 18. Treatment planning consisted of three-dimensional (3-D) conformal RT in 49 (40%) patients including nine patients irradiated using arytenoid protection. A median dose of 70 Gy (60-74 Gy) was given (2 Gy/fraction) over a median period of 46 days (21-79 days). Median follow-up period was 85 months. RESULTS: The 5-year overall, cancer-specific, and disease-free survival amounted to 80%, 94%, and 70%, respectively. 5-year local control was 83%. Median time to local recurrence in 19 patients was 13 months (5-58 months). Salvage treatment consisted of surgery in 17 patients (one patient refused salvage and one was inoperable; total laryngectomy in eleven, and partial laryngectomy or cordectomy in six patients). Six patients died because of laryngeal cancer. Univariate analyses revealed that prognostic factors negatively influencing local control were anterior commissure extension, arytenoid protection, and total RT dose < 66 Gy. Among the factors analyzed, multivariate analysis (Cox model) demonstrated that anterior commissure extension, arytenoid protection, and male gender were the worst independent prognostic factors in terms of local control. CONCLUSION: For early-stage laryngeal cancer, outcome after RT is excellent. In case of anterior commissure extension, surgery or higher RT doses are warranted. Because of a high relapse risk, arytenoid protection should not be attempted.

Histological expression of tumour necrosis factor-related apoptosis-inducing ligand (TRAIL) in human primary melanoma.

AIMS: Tumour necrosis factor-related apoptosis ligand (TRAIL) appears to selectively induce apoptosis in a wide range of cultured malignant cells, including melanoma. This study was designed to attempt to clarify the role of TRAIL in the biology of human melanoma. METHODS: Tissue sections cut from formalin-fixed, paraffin-embedded tissue blocks of 45 primary cutaneous melanomas were tested for expression of TRAIL using immunohistochemistry. The intensity, pattern of staining and percentage of positively stained tumour cells were evaluated in each melanoma. Breslow thickness, ulcerative state, dermal mitotic rate and the presence of tumour infiltrating lymphocytes were measured/determined in each case. Median follow up for the cohort of patients was 10 months (range 1-18). Survival analysis was conducted using the Kaplan-Meier method. The level of expression of TRAIL was compared with the various histological determinants using the two-tailed Fisher's exact test and the chi2-test. RESULTS: Overall and disease-free survival were 72 and 48%, respectively, and did not correlate with TRAIL expression. Among the pathological prognostic determinants, only mitotic rate showed a statistically significant correlation with TRAIL expression using the chi2-test (P=0.04). CONCLUSION: We conclude that TRAIL expression in melanoma defines a more aggressive/proliferative phenotype, either through selection of apoptotic resistant cells or by secondary induction of other factors enhancing proliferation of more malignant cells. Analysis of a larger group of patients with longer follow-up is required to determine whether TRAIL expression correlates with survival of patients.

Extent of parotid disease influences outcome in patients with metastatic cutaneous squamous cell carcinoma.

OBJECTIVES: To test a new clinical staging system in patients with metastatic cutaneous squamous cell carcinoma involving the parotid gland or lymph nodes of the neck. DESIGN: Retrospective analysis of clinicopathological data from patients with a minimum of 2 years' follow-up. SETTING: Multidisciplinary head and neck unit in a tertiary referral center. PATIENTS: Between 1987 and 1999, 126 patients (104 men and 22 women; median age, 69 years) were treated for metastatic cutaneous squamous cell carcinoma involving the parotid and/or neck. MAIN OUTCOME MEASURES: Locoregional recurrence and disease-specific survival. RESULTS: Of the 126 patients, disease involved the parotid gland in 81 patients, of whom 14 also had clinical neck disease, while 45 patients had neck involvement only. Parotid stages were as follows: P0, 45 patients; P1, 55; P2, 20; and P3, 6. Neck stages were: N0, 67 patients; N1, 31; and N2, 28. Treatment involved combined surgery and radiotherapy in 93 patients, surgery alone in 12, and radiotherapy alone in 18. Three patients received palliative treatment only. There were 47 therapeutic and 40 elective neck dissections. Pathologic evaluation demonstrated parotid involvement in 70 patients and neck involvement in 51, representing 44 therapeutic and 7 elective neck dissections. Disease involved both the parotid and neck in 19 patients. The 5-year local (parotid) control rate was 80% and this varied statistically significantly with P stage. Parotid stages 2 and 3 were independent risk factors for a decrease in local control rate using multivariate analysis. The 5-year disease-specific survival rate for the entire group was 68% and P stage significantly influenced survival: P0, 60%; P1, 81%; P2, 51%; and P3, 33% (P<.001). Pathological involvement of neck nodes did not worsen survival of patients with parotid disease. Overall multivariate analysis demonstrated that single-modality therapy, P3 stage, and presence of immunosuppression independently predicted a decrease in survival. CONCLUSIONS: These results confirm that the extent of metastatic disease in the parotid gland significantly influences outcome and suggests that staging the parotid separately in metastatic cutaneous squamous cell carcinoma may be useful. Further evaluation of the recommended staging changes with a larger patient cohort will be required to clarify the influence of neck node involvement.

Primary and metastatic cancer of the parotid: comparison of clinical behavior in 232 cases.

OBJECTIVES/HYPOTHESIS: Parotid malignancy may develop as a primary cancer of salivary tissue or by metastatic involvement of parotid lymph nodes. The aim of the study was to compare the clinical behavior of primary and metastatic parotid cancers by analyzing patterns of treatment failure and clinical outcomes. STUDY DESIGN: Retrospective review of clinical and pathologic data prospectively accessioned onto a computerized database. METHODS: A prospectively documented series of 232 parotidectomies carried out for treatment of cancer from 1988 to 1999 was reviewed. There were 177 male and 55 female patients with a median age of 65 years (age range, 17-97 y). Median follow-up time was 4 years. Pathological groups included 54 patients with primary parotid cancer, 101 with metastatic cutaneous squamous cell carcinoma, 69 with metastatic melanoma, and 8 with other metastatic cancers. RESULTS: Neck nodes were clinically positive in 12 patients with primary cancer, 24 patients with squamous cell carcinoma, 16 with melanoma, and 2 with other metastatic malignancies. Conservative parotidectomy, preserving the main trunk of the facial nerve, was performed in 185 patients, and 47 patients had a radical parotidectomy sacrificing the facial nerve. There were 54 therapeutic and 110 elective neck dissections. Adjuvant radiotherapy was given to 39 patients with primary cancer, 86 with squamous cell carcinoma, 50 with melanoma, and 8 in the other metastatic group (78% of the patients in the series). Local control rates at 5 years in the four groups were 86%, 75%, 94%, and 100%, respectively (P <.01). Survival rates at 5 years were 77%, 65%, 46%, and 56%, respectively (P <.01). CONCLUSIONS: The pattern of parotid malignancy is unique in Australia because of the high incidence of skin cancer, which can metastasize to the parotid gland. Metastatic cutaneous malignancy predominates. The pattern of failure and outcome varied depending on histological findings. Local failure occurred most often in metastatic squamous cell carcinoma, whereas patients with melanoma had the highest incidence of distant spread.

Clinical outcome following total laryngectomy for cancer.

BACKGROUND: Patients with advanced cancers of the larynx and hypopharynx have been treated with total laryngectomy at the Department of Head and Neck Surgery, Royal Prince Alfred Hospital, Sydney in the past. Increasingly, these patients are being managed with organ-sparing protocols using chemo-therapy and radiotherapy. The aim of the present study was to review complication, recurrence and survival rates following total laryngectomy. METHODS: Patients who had total laryngectomy for squamous carcinomas of the larynx or hypopharynx between 1987 and 1998 and whose clinicopathological data had been prospectively accessioned onto the computerized database of the Department of Head and Neck Surgery, Royal Prince Alfred Hospital, were reviewed. Patients whose laryngectomy was a salvage procedure for failed previous treatment were included. RESULTS: A total of 147 patients met the inclusion criteria for the study, including 128 men and 19 women with a median age of 63 years. Primary cancers involved the larynx in 90 patients and hypopharynx in 57. There were 30 patients who had recurrent (n = 24) or persistent disease (n = 6) after previous treatment with radiotherapy (26 larynx cases and four hypopharynx cases). Pharyngo-cutaneous fistulas occurred in 26 cases (17.7%) and, using multivariate analysis, the incidence did not correlate with T stage, previous treatment or concomitant neck dissection. Local control rates were 86% for the larynx and 77% for the hypo-pharynx groups and neck control was 84% and 75%, respectively. Five-year survival for the larynx cancer group was 67% and this was significantly influenced by T stage and clinical and pathological N stage. Survival in the hypopharynx group was 37% at 5 years and this did not significantly correlate with T or N stage. There was a non-significant trend to improved survival among previously treated patients whose laryngectomy was a salvage procedure. CONCLUSION: Patients with cancer of the larynx had a significantly better survival following total laryngectomy than patients with hypopharyngeal cancer. Those whose laryngectomy was carried out as a salvage procedure following failed previous treatment did not have a worse outcome than previously untreated patients.

Functional analysis after supracricoid partial laryngectomy with cricohyoidoepiglottopexy.

OBJECTIVES: To assess prospectively speech and swallowing function in a series of 17 patients after supracricoid partial laryngectomy with cricohyoidoepiglottopexy. STUDY DESIGN: Retrospective study. METHODS: From 1983 to 1996, 69 patients at Department of Otolaryngology-Head and Neck Surgery, CHUV (Lausanne, Switzerland) underwent a supracricoid partial laryngectomy with cricohyoidoepiglottopexy. Seventeen of them (25%) could be contacted and accepted participation in a functional evaluation that included a questionnaire to document their present nutritional status and diet. A formal voice evaluation was also performed, which included psychoacoustic evaluation of vocal qualities, fundamental frequency parameters, phonation intensity range, phonatory quotient (vital capacity divided by maximum phonation time), and a laryngeal video laryngoscopy performed with a rigid endoscope. RESULTS: Median postoperative follow-up was 66 months (range, 12-152 mo). Nine of 17 patients (53%) recovered a normal diet with no increased incidence of aspirations. Seven of 17 had minor limitations such as no peanuts, dry bread, or rice. Two of 17 patients were restricted to pureed food. Assessment of voice showed a clearly decreased mean fundamental frequency at 70.1 Hz (normal range, 121-211 Hz) and a narrowed frequency range of phonation with a mean value of 8.8 semitones (normal value, 27). Forty-two percent of the patients went back to their normal professional life after the operation. Among the 10 who did not, 3 (16%) retired and 7 actually had to give up their profession, because of the modification of their voice or general asthenia and age close to retirement. CONCLUSION: Restoration of laryngeal function after supracricoid partial laryngectomy with cricohyoidoepiglottopexy is satisfactory. Although most of the patients seem to recover normal swallowing function, severe voice alterations appear to be inevitable.
