Trends in Systemic Inflammatory Reaction (SIR) during Paclitaxel and Carboplatin Chemotherapy in Women Suffering from Epithelial Ovarian Cancer.

BACKGROUND: Epithelial ovarian cancer (EOC) is the most fatal gynaecological malignancy treated with cytoreductive surgery followed by adjuvant taxane-platinum-based chemotherapy. It has been shown that the pretreatment systemic inflammatory reaction (SIR) in women with OC can be evaluated using the neutrophil-to-lymphocyte ratio (NLR), lymphocyte-to-monocyte ratio (MLR), platelet-to-lymphocyte ratio (PLR) and systemic inflammatory index (SII), depending on the stage of disease, and has prognostic value for overall survival. The aim of this study was to evaluate the changes in NLR, LMR, PLR and SII during chemotherapy. METHODS: A total of 107 women with EOC (23 with type I and 84 with type II tumours) were included in a retrospective single-centre analysis. The Kologomorov-Smirnoff, Kruskal-Wallis or Friedman analysis of variance tests were used for data analysis, and a p value of 0.05 was considered statistically significant. RESULTS: A significant decrease in NLR, PLR and SII but not LMR was observed during adjuvant treatment. Pretreatment NLR, PLR and SII were dependent on disease stage and tumour grade; however, this association was lost during therapy. Additionally, strong and positive mutual correlations between NLR, LMR, PLR and SII were sustained during the whole course of chemotherapy. CONCLUSIONS: During first-line adjuvant chemotherapy in women with EOC, a decrease in SIR is confirmed.

Outcomes and Prognostic Factors in the Treatment of Intracanalicular Vestibular Schwannomas Using Gamma Knife Stereotactic Radiation.

BACKGROUND: No gold standard has been developed for the therapy of intracanalicular vestibular schwannomas (IVS). Options for treatment include a conservative approach, microsurgery, or radiosurgery. Although the efficacy of these treatment has been well-documented, little is known about the determinants of outcome in IVSs following radiosurgery. Therefore, we examined the results in relation to age, gender, tumor volume, distance to fundus, microcyst existence, and radiosensitivity in this group. In addition, we investigated possible predictors of facial nerve function and hearing preservation. METHODS: Ninety-four patients with unilateral IVS were included in the evaluation (52 women and 42 males). The patients were separated into younger and older age groups based on their median age (55 years). The median IVS volume was 138 mm3, microcysts were identified in 16 tumors, and 63 tumors were adjacent to the fundus. The data were analyzed using Statistica software package ver. 13.3. RESULTS: At final follow-up, a statistically significant decrease in tumor volume and no statistically significant decline in hearing were noted, but no differences between age groups were found. The sex had no effect on overall tumor growth control, facial nerve preservation, or hearing preservation. Localization of IVS close to the fundus and the presence of tumor microcysts had no effect on the control of tumor growth, preservation of hearing, and sparing of facial nerve following radiosurgery. Cochlear dose had no influence on hearing preservation. Higher tumor volume was associated with its pseudoprogression during early follow-up and a greater risk of hearing loss. CONCLUSIONS: Age, sex, tumor volume, proximity to the fundus, and the existence of a microcyst were not predictive of radiosensitivity nor preservation of facial nerve function and hearing, based on the findings. There was no effect of cochlear dose on hearing. Initial greater tumor volume was associated with an increased probability of tumor pseudoprogression.

Narrow-band imaging vs Lugol chromoendoscopy in screening for esophageal squamous cell neoplasia: a randomized trial.

INTRODUCTION: To date, there is no established optimal method for endoscopic detection of esophageal squamous cell neoplasia in high­risk individuals. OBJECTIVES: We aimed to compare the performance of narrow­band imaging (NBI) and Lugol chromoendoscopy in screening for esophageal neoplasia among patients with a history of treatment for head and neck squamous cell cancer (HNSCC). PATIENTS AND METHODS: We randomly assigned 300 patients who had completed curative treatment for HNSCC at least 1 year prior to the inclusion to undergo either NBI or Lugol endoscopy (2:1 ratio). Following white­light examination of the esophagus, the assigned imaging study was performed, and biopsies were taken from any suspicious lesions identified using NBI or Lugol chromoendoscopy. The primary end point was positive predictive value (PPV) of the biopsied lesion for a diagnosis of esophageal neoplasia (high­grade intraepithelial neoplasia [HG­IEN] or invasive esophageal squamous cell carcinoma [ESCC]). The secondary end points included the number of biopsied lesions, duration of esophagus examination, and endoscopy tolerance. RESULTS: In 294 patients included in the final analysis (NBI, n = 204; Lugol chromoendoscopy, n = 90), we diagnosed 3 ESCCs (1.02%) and 2 HG­IENs (0.68%). The PPV of NBI and Lugol chromoendoscopy in per­lesion analysis was 7.69% (95% CI, 0.94%-25.1%) and 8.11% (95% CI, 1.7%-21.9%), respectively (P >0.99). NBI outperformed Lugol chromoendoscopy in terms of the rate of patients requiring biopsy (12.75% vs 41.11%; P = 0.003), duration of esophagus examination (3.5 min vs 5.15 min; P <0.001), and endoscopy tolerance assessed on the visual analog scale (25 mm vs 36.5 mm; P = 0.002). CONCLUSIONS: With a PPV comparable to that of Lugol chromoendoscopy, but a lower number of biopsies required, shorter examination time, and better patient tolerance, NBI could be considered the primary screening method for ESCC in patients with HNSCC.

Prognostic value of human papillomavirus detection and the eighth edition of the TNM classification staging system in oropharyngeal squamous cell carcinoma: A single-center Polish study.

OBJECTIVES: This study aimed to determine human papillomavirus (HPV) status and genotypes, the HPV status-dependent survival, and the applicability of the eighth TNM classification in Polish patients diagnosed with oropharyngeal squamous cell carcinoma (OPSCC). STUDY DESIGN: All patients with primary OPSCC, diagnosed and treated from 2007 to 2017 at the National Research Institute of Oncology, Warsaw, Poland, who underwent radical radiotherapy were included. The Kaplan-Meier method was deployed to produce 3- and 5-year observed survival (OS) estimates. RESULTS: A total of 110 OPSCC cases were identified. Double positivity for HPV (IHC p16INK4a and HPV-DNA) was recorded in 70.9% of cases, with HPV16 being the most prevalent genotype (96.2%). The disease stage was significantly less advanced in the HPV-related group than in the HPV-negative group (P < .001). Three- and 5-year OS in HPV-related carcinoma was 80.7% and 74.0%, respectively; in the HPV-negative group, OS was 52.9% and 48.5%. OS rates were associated with HPV status, tumor stage, and disease stage according to the eighth edition TNM classification. CONCLUSIONS: The majority of Polish patients with OPSCC are HPV16-positive. In HPV-related OPSCC, survival rates are significantly higher than in HPV-negative OPSCC. The findings support the requirement of HPV testing in Polish patients with OPSCC because HPV-positive status influences tumor prognosis.

Effectiveness of the No action level protocol for head & neck patients - Time considerations.

BACKGROUND: The No Action Protocol (NAL) was used to diminish the systematic set-up error. Recently, owing to the development of image registration technologies, the on-line positioning control is more often used. This method significantly reduces the CTV-PTV margin at the expense of the lengthening of a treatment session. The efficiency of NAL in decreasing the total treatment time for Head&Neck patients was investigated. METHODS: Results of set-up control of 30 patients were analyzed. The set-up control was carried out on-line. For each patient and each fraction, the set-error and the time needed for making the set-up control procedure were measured. Next, retrospectively, the NAL was applied to this data. The number of initial errors (without interventions) and after NAL protocol were compared in terms of errors larger than 3 and 4 mm. The average and total time used for portal control was calculated and compared. RESULTS: The number of setup errors in the posterior-anterior, inferior-superior, and right-left directions ≥3 mm and ≥4 mm were 98, 79, and 91 sessions and 44, 38 and 30 sessions out of 884 sessions. After NAL protocol the number of errors ≥3 mm and ≥4 mm decreased to 84, 57, and 39 sessions and 31, 15 and 10 sessions, respectively. The average time needed for one set-up control was 5.1 min. NAL protocol allows saving 4049 min for the whole group. CONCLUSIONS: For locations where the random set-up errors are small, the NAL enables a very precise treatment of patients. Implementation of this protocol significantly decreases the total treatment time.

Human cytomegalovirus and Epstein-Barr virus infections increase the risk of death in patients with head and neck cancers receiving radiotherapy or radiochemotherapy.

Viral infections, including cytomegalovirus (CMV) and Epstein-Barr virus (EBV), play an important role in carcinogenesis and can influence patients' prognosis and condition during cancer treatment.The goal of this study was to investigate CMV and EBV infections in patients receiving radiotherapy or radiochemotherapy due to head and neck cancers to determine the influence of these infections on the risk of death. The observation period was 2 years.Of 41 patients enrolled, 11 received radiotherapy (simultaneous-integrated boost intensity-modulated radiation therapy [SIB-IMRT], 2.25 Gy/fraction, 30 fractions, [n = 7] or IMRT, 2 Gy per fraction, 35 fractions, [n = 4]) and 30 received radiochemotherapy (cisplatin 100 mg/m and SIB-IMRT [n = 13] or IMRT [n = 17]). Plasma CMV and EBV DNA levels were assessed using real-time PCR before or during treatment or 4 weeks posttreatment.The risk of death in the group positive for plasma CMV or EBV deoxyribonucleic acid (DNA) was significantly higher compared to the group without detectable plasma CMV (odd ratio [OR]: 7.5, 95% confidence interval [CI]: 1.11-50.67) or EBV DNA (OR: 10.91, 95% CI: 1.135-104.8). Results were confirmed using the Bayesian method. Plasma positivity for CMV or EBV DNA was associated with a higher risk of death (both P = .04).Viral infections negatively affect the survival of patients with head and neck cancers. Diagnosing and treating these viral infections in patients with positive results should be considered.

Evaluation of efficacy of Caphosol in prevention and alleviation of acute side effects in patients treated with radiotherapy for head and neck cancers.

AIM OF THE STUDY: Oral mucositis is a common side effect of the oral mucosa due to anticancer therapy, especially for head and neck cancer. Caphosol is indicated for dryness of the mouth and oropharynx and treatment of mucositis due to irradiation or high-dose chemotherapy. The aim of the study was to evaluate the efficacy of Caphosol in preventing and alleviating mucositis due to radiotherapy in the head and neck region. MATERIAL AND METHODS: Caphosol was used from the beginning of the irradiation and for two weeks more after the treatment was completed. Mucositis, xerostomia, and dysphagia were scored by radiotherapists. Subjective evaluation was made by patients. Caphosol was assessed in a non-blinded, matched clinical study. Each treatment arm consisted of 50 patients. The groups were similar. The only difference in the management protocol between the treatment arms was the use of Caphosol in the experimental arm. RESULTS: A statistically significant difference in mean severity of early irradiation-induced side effects between the studied groups was observed with respect to: mucositis in the clinical target volume (CTV) area, mucositis in the increased dose (boost) area, dysphagia and xerostomia (p < 0.001 for all reactions). In the group of patients who used Caphosol, the mucositis was less intense, both in the CTV and in the boost area. CONCLUSIONS: The use of Caphosol reduces the severity of acute mucositis, dysphagia and xerostomia, exerting a positive effect on comfort in the oral cavity in patients irradiated for head and neck tumors.

Tracheal adenoid cystic carcinoma mimicking a thyroid tumor: A case report.

At present, only eight cases of tracheal adenoid cystic carcinomas (ACCs) mimicking thyroid tumors have been reported. Since there are no guidelines available regarding their diagnosis and treatment, they present a significant clinical challenge. In the present study, patient treatment was analyzed to deliver the first concise summary of treatment options in patients with ACC mimicking a thyroid tumor. In addition, all available data regarding molecular abnormalities of this disease have been discussed. The current study presents a case of a 17-year-old patient with a tracheal ACC mimicking a thyroid tumor. The patient was diagnosed in 2007 with a pathological mass between the left lobe of the thyroid and the trachea, and underwent surgery and radiotherapy. In 2010, multiple lesions in the lungs were diagnosed and pulmonary metastasectomy was performed. Following surgery, the patient has been disease-free for almost 30 months. Thyroid tumor biopsy may reveal ACCs. This pathological report requires further investigation of the head and neck in order to confirm if the disease is of tracheal origin. Patients may present with a neck swelling, hoarseness of voice or dysphagia. Surgery must be considered as first-line therapy for all patients with local disease as it may be curative. For palliative treatment chemoradiotherapy based on cisplatin may be effective. The identification of cytogenetics, tumor suppressor genes, oncogenes, epigenetic alterations and mitochondrial abnormalities specific for ACCs is critical to the development of targeted therapies. Thus far, large studies have only reported the transcriptional activator Myb and mammalian target of rapamycin signaling pathway to be disrupted in ACCs.

[The results and toxicity of organ preservation treatment for locoregionally advanced laryngeal and hypopharyngeal cancer]. / Ocena wyników i tolerancji zachowawczego leczenia oszczedzajacego narzad u chorych na lokoregionalnie zaawansowanego raka krtani i krtaniowej czesci gardla.

UNLABELLED: The most frequent malignant tumor of the head and neck region is a squamous cell cancer of the larynx. Squamous cell cancer of the hypopharynx is diagnosed rarely, but it has poorer prognosis than laryngeal cancer. The surgical treatment, especially in advanced disease, is a laryngectomy with the definitive tracheostomy, what negatively influenced the quality of life. Therefore, oncologists have been interested in new alternative methods of conservative treatment from many years. THE AIM OF THE STUDY: The evaluation of efficacy and toxicity of the organ preservation treatment in patients with locally advanced laryngeal and hypopharyngeal cancer. MATERIAL AND METHODS: The patients with diagnosed squamous cell laryngeal and hypopharyngeal cancer in III and IVa clinical status were treated with concomitant radiochemotherapy with intention of the organ preservation. Conformal 3D radiotherapy and SIB-IMRT technique was applied in all cases. Concomitant chemotherapy consisted of cisplatin in daily dose100mg/m(2) given two times during irradiation (1 and 22 day of treatment) or once weekly in dose 40mg/m(2). Between January 2004 and November 2008 146 patients were treated with this method. There were 83 patients diagnosed with laryngeal cancer and 62 patients with hypopharyngeal cancer in this group. RESULTS: The median follow up is 42 months. Five years overall survival is 75% and disease free survivak is 63%. Three years laryngectomy free survival (LFS) is 82% and 5-years LFS is 76%. This group of patients is alive with larynx preservations. In 17.3% patients local recurrence was observed (4.5% regional recurrence and 1.8% locoregional). Those patients underwent salvage surgery or were treated with palliative chemotherapy. No severe life risking early and late complications were observed. Only 7% of patients have required temporary tracheostomy because of difficulties in breathing due to larynx edema. CONCLUSION: We can conclude that organ preservation treatment is a valuable alternative to surgical procedure in patients diagnosed with laryngeal and hypopharyngeal cancer in III and IVa clinical status.

[The results of combined treatment patients with olfactory neuroblastoma in material of Cancer Center in Warsaw]. / Wyniki skojarzonego leczenia nerwiaka wechowego (olfactory neuroblastoma) w materiale Centrum Onkologii w Warszawie.

UNLABELLED: The results of combined treatment patients with olfactory neuroblastoma in material of Cancer Center in Warsaw AIM: The analysis of the results of combined treatment patients with olfactory neuroblastoma in material of Cancer Center in Warsaw. MATERIAL: Authors present material of 27 cases olfactory neuroblastoma treated in Cancer Center of Warsaw from 1965 to 2008. The median age was 44 years (range 10-74). The median observation was 72 months (range 2-235).The tumors were seen in 15 women and 12 men. According to Kadish staging there were one A, eight B, and seventeen C stage tumor. The patients in stage A and B was treated by surgery and radiotherapy (mean dose in whole material was 57.15 Gy range 44-70). Five patients in stage C was treated by surgery, radiotherapy and adjuvant chemotherapy. Five patients were treated by neoadjuvant chemotherapy and radiotherapy. Six patients underwent surgery and radiotherapy. One patient was died during adjuvant chemotherapy. One patient in stage B had local recurrence, one local recurrence and metastases and one had only metastases. In stage C 4 patients was died because of metastases, one had local recurrence and, 3 was died because of other reasons. Patients who was failed, underwent surgery, chemotherapy or radiotherapy, it was dependent of clinical situation. RESULTS: A complete regression was seen in 100% patients in early stages (A and B) and 82% patients in stage C. The 5-year local progression-free survival rate was 91% in early stages and 60% in stage C. The LPFS in whole group was 66.7%. The 5-year disease-free survival rate was 91% in early stages, 46% in stage C. The DSF rate in whole group was 44.4%. The 5-year overall survival rate was 80% in stages A and B, 41.2% in stage C. The OS in whole group was 55.6%. The 5-year survival rate was 20% for patients who had recurrence and/or metastases. CONCLUSION: A combination of surgery and radiotherapy appears to be adequate treatment for early stages (A and B) olfactory neuroblastoma. There are still no clear protocols of treatment patients in stage C.

[SIB-IMRT radiotherapy given concomitantly with cisplatin for locally advanced squamous cell head and neck cancer (SCHNC). Evaluation of the early results and toxicity]. / Zastosowanie techniki SIB-IMRT w leczeniu skojarzonym z jednoczesna chemioterapia u chorych na nowotwory glowy i szyi w III i IVa stopniu zaawansowania. Ocena wczesnych wyników i tolerancji leczenia.

UNLABELLED: Concomitant radiochemotherapy become the treatment of choice for locally advanced SCHNC. This strategy of treatment has a limitation, which is an acute and late toxicity. The IMRT technique provides the possibility of better sparing of healthy tissue. Radiobiological and clinical data also suggest that accelerated fractionation and higher dose per fraction given in GTV may produce better locoregional control. Therefore it might be expected that concomitant chemotherapy and SIB-IMRT radiotherapy could increase locoregional control and reduce acute and late radiation reactions. The evaluation of early results and toxicity of this treatment modality is presented. AIM OF STUDY: The evaluation of the early results and toxicity of SIB-IMRT radiotherapy given concomitantly with cisplatin for locally advanced squamous cell head and neck cancer (SCHNC). METHODS: SIB-IMRT technique was applied. The boost volume was limited to the GTV + 3mm margin (macroscopic tumor extension was defined on the basis of CT and/or MRI examinations). Dose per fraction given to this volume was 2.25 Gy up to 67.5 Gy of total dose. The PTV-CTV + 3mm - was defined as an area of increased risk of microscopic spread. Dose per fraction given to this volume was 2 Gy up to 60 Gy. The PTV1-ETV+ 3mm (electively irradiated volume) received dose per fraction -1.8 Gy up to 54-56 Gy. Overall treatment time was 6 weeks (5 fractions per week, 30 fractions). Concomitant chemotherapy consisted of cisplatin in daily dose100mg/m2 given two times during irradiation (1 and 22 day of treatment). The evaluation of early tolerance was performed once weekly during the treatment than during the follow up every 2 months. The early reactions were scored according to the EORTC/RTOG scale. MATERIAL: Between June 2006 and December 2009 99 patients diagnosed with III and IV clinical stage of SCHNC were treated with this method. 65 patients were diagnosed with oropharyngeal cancer, 18 with laryngeal cancer and 16 with hypopharyngeal cancer. PEG was performed at 65 patients before treatment for better alimentation during radiochemotherapy. RESULTS: No severe life risking complications were observed a no concequentional late effects were observed. Extended mucositis grade III according RTOG/EORTC scale were observed only in boost region in 80% patients just after treatment was completed. In 2 patients ulceration were observed in tumour side which have healed up spontaneously within two months after treatment. 55% patients were suffering for III xerostomia and 41% for middle after the treatment. Majority of side effects were cured within 4 months after irradiation. The PEG was removing in 92% patients 2 months after treatment. The median follow-up time is 28 months (ranged from 14 m to 58 m). Actuarial 2-years overall survival and disease-free survival is respectively 90% and 82%, probability of locoregional recurrence at 2-years is 14% and 5-years estimated is 17,5%. CONCLUSIONS: At the present moment it might be concluded that accelerated radiotherapy with SIB-IMRT given concomitantly with cisplatin produce excellent local control in patients treated of III-IV stage SCHNC without increasing toxicity.

[Strategy of combined treatment in patient with cancer of paranasal sinuses]. / Strategia leczenia skojarzonego chorych na nowotwory zatok przynosowych.

Cancers of pranasal sinuses are rare neoplasms in humans. In 2003, in Poland there were 132 new patients diagnosed for this disease. Squamous cell cancer is the most frequent one in this region. Other types of cancer in this region are adenocarcinoma (about 30%), carcinoma adenoides cysticum or neoplasms such as rhabdosarcoma, chondrosarcoma, lymphoma or melanoma malignum. There is a very rare neoplasm as a olfactory neuroblastoma in this localization. Cancer of the paranasal sinuses infiltrates only locoregionally. Metastases to the lymph nodes are seldom--below 30%; this is why elective lymphangiectomy or irradiation are not obligatory treatment in this case. The most important is histopathological verification performed by biopsy. For clinical staging it is obligatory to perform endoscopy, CT or MR examination. The treatment of cancers of paranasal sinuses is always surgery with adjuvant irradiation. The modern radiotherapy techniques provide the possibility to spare healthy tissues and organs at risk. The organs at risk in this localization are optical nerves and chiasm, and parotid glands. The conformal radiotherapy is used most frequently. In case of the tumour being of complex shape and located in the vicinity of the organs at risk the IMRT technique is used. The radiation treatment combined with chemotherapy is applied in cases of not radical surgery in the region of ethmoides sinuses.

[Concomitant radiochemotherapy followed by adjuvant chemotherapy in patients with poorly differentiated nasopharyngeal cancer; tolerance and early results of treatment]. / Ocena tolerancji i wczesnych wyników jednoczesnej radiochemioterapii i uzupelniajqcej chemioterapii u chorych na nisko zróznicowane raki nosowej czesci gardla.

INTRODUCTION: Recently, concomitant radiochemotherapy became a method of choice in patients with poorly differentiated nasopharyngeal cancer. The aim of this study is to estimate tolerance and early results of the concomitant radiochemotherapy followed by adjuvant chemotherapy (modified US Head and Neck Intergroup protocol). METHODS AND MATERIAL: Analysing protocol consist of conventionally fractionated radiotherapy (TD = 70 Gy) given concomitantly with cisplatin (30 mg/m2 daily during 3 days every 3 weeks). This part of treatment was followed by 3 courses of PF (cisplatin + 5-fluorouracil) chemotherapy. Between August 1998 and September 2003 thirty six patients (27 male and 9 female) were qualified to treatment. Median age was 33 years. RESULTS: Tolerance of concomitant radiochemotherapy was acceptable. Intensive mucosal acute reactions (>G2) were observed in 67% patients. Life threatening complications (sepsis + DIC) was observed in single case. All patients received radiotherapy in planned total dose. Eighty six percent of patients received cisplatin in planned cumulated doses. Tolerance of the adjuvant chemotherapy was worse. Only 44% patients received all three courses of PF chemotherapy. The reasons of incomplete chemotherapy were neutropenia, infections, prolongated acute reactions or performance status decreasing. Complete regression was obtained in 86% patients. Two years overall and disease free survival rates were 83% and 72%, respectively. CONCLUSIONS: Our results confirm high activity of the concomitant radiochemotherapy followed by chemotherapy in patients with poorly differentiated nasopharyngeal cancer. Those results confirm also high toxicity of this regimen, what suggest very careful patients qualification to treatment.

[Cancer in branchiogenic cyst--primary focus or metastasis?]. / Rak w obrebie torbieli bocznej szyi--proces pierwotny czy przerzut?

The authors report the case of 68 year old male operated upon for the branchial cyst of the neck. Histopathological examination showed carcinoma in the wall of the cyst. Ipsilateral tonsillectomy was done and pathology revealed primary focus in the palatine tonsil. Diagnosis of the branchiogenic cancer should be made only when all the criteria defined by Martin in 1950 are met. Patients with carcinoma cells found in branchial cyst should be diagnosed and treated as metastasis from Waldeyer's ring to the lymph nodes of the neck. Ipsilateral tonsillectomy is indicated as blind biopsy. When histopathological examination of the tonsil is negative the patients should be treated as metastasis to the neck from unknown primary focus.
