[Orbital mantle cell lymphoma succesfully treated by Bcl-2 inhibitor: Report of a case]. / Lymphome du manteau orbitaire traité avec succès par un inhibiteur de Bcl-2 : à propos d'un cas.

Lymphoma is the most common orbital malignancy in adults. Among the types of lymphoma, mantle cell lymphoma is a particularly aggressive form, often discovered through systemic involvement, with a dismal prognosis due to frequent recurrences. It is secondary to a t (11 ; 14) (q13; q32) chromosomal translocation resulting in an anti-apoptotic signal via overexpression of Bcl-2. Treatment is based on R-CHOP poly-chemotherapy. We describe the case of a patient with an orbital recurrence of mantle cell lymphoma successfully treated with oral Bcl-2 inhibitor monotherapy. A 58-year-old man who was treated with R-CHOP 8 years ago for mantle cell lymphoma, in remission for 5 years, presented with progressive decreased visual acuity in the left eye, along with binocular diplopia. Clinical examination revealed a decrease in visual acuity in the left eye to 1/20 Parinaud 20 and a relative afferent pupillary defect on the left. External examination revealed a left cranial nerve VI palsy, 2mm of painless proptosis, and hypesthesia of the left V1 territory, leading to a diagnosis of left orbital apex syndrome. The disc and macular OCT were normal. The visual field showed enlargement of the left blind spot. An emergency CT scan and MRI revealed an apical extraconal tissue mass infiltrating the medial rectus muscle, extending to the superior orbital fissure, optic canal and left cavernous sinus, hyperintense on T2 weighted images and isointense on T1. The morphological appearance was strongly suggestive of an infiltrative lymphomatous process. An 18 FDG PET-scan identified the orbital lesion as well as enhancing lesions in the axilla and colon; given the clinical features and test results, the diagnosis of recurrent mantle cell lymphoma was made without biopsy. Treatment with Venetoclax (Bcl-2 inhibitor) was initiated. At one month of treatment, the orbital apex syndrome had entirely resolved, with visual acuity increased to 8/10 Parinaud 4 and a metabolic return to normal on PET scan. The PET scanner and clinical examination at 3 months were entirely normal. At the one-year follow-up visit, the patient was still on Venetoclax, the clinical examination was unchanged, and the PET-scan still showed a complete metabolic response.

Description of late onset neutropenia in indolent lymphoma patients treated with bendamustine plus rituximab.

Bendamustine (B) associated with rituximab (R) is widely described in literature for the management of patients with chronic lymphoid leukaemia (CLL) and indolent non-Hodgkin lymphoma. Safety data regarding late hematotoxicity such as late onset neutropenia (LON) are scarce. The aim of our study was to assess the incidence and to identify risk factors for LON in patients with indolent non-Hodgkin lymphoma and CLL treated with B and R (B-R). One hundred forty five patients were treated with B-R as first or second line. Patients with neutropenia prior induction treatment, treated beyond second line and relapsing within 3 months after the end of induction treatment, were excluded. Patients receiving at least 1 cycle of B-R and having LON during follow-up period were included and considered as eligible for toxicity assessment. A complete blood count was performed 4 weeks after the last cycle of induction treatment and thereafter every 3 months for 1 year. Thirty six patients were identified in our cohort (incidence of 25%), mostly affected by CLL (n = 11) and follicular lymphoma (FL) (n = 15). During follow-up, 84 events of LON were recorded, 61% and 39% were of grades 1/2 and 3/4, respectively. No episode of febrile neutropenia was documented. Amongst 13 of the 15 patients with FL undergoing R maintenance, 8 had treatment discontinuation because of LON. Median time for LON (grade > 2) and time to recovery (grade < 3) were of 11.2 and 17.3 weeks, respectively. One year after B-R induction, LON persisted in 4 patients. The risk of LON was increased both in patients with FL or CLL and performance status >1. The LON in B-R treated patients is clinically relevant. Close clinical and biological follow-up and treatment prophylaxis (eg, valaciclovir and cotrimoxazole) especially for FL patients undergoing maintenance with R monotherapy seems relevant.

[Reirradiation of head and neck cancers]. / Réirradiation des cancers des voies aérodigestives supérieures.

Locoregional relapse in previously irradiated region for head and neck tumours is associated with a bad locoregional and distant prognosis. Reirradiation might be exclusive, or feasible in addition with surgery and/or chemotherapy, according to histopronostic factors. Data show that reirradiation is feasible with some severe toxicity due to the bad prognosis of this situation. Hyperfractionnated regimen with split course or normofractionnated regimen without split course are possible with similar efficacy. If tumour size is small, stereotactic ablative radiotherapy may be considered, and if the treatment centre has proton therapy, it could be proposed because of better organs at risk sparing. There is no standard regarding reirradiation schedules and several trials have to be done in order to determine the best technique. Nevertheless, it is agreed that a total dose of 60Gy (2Gy per fraction) is needed. Other trials testing the association with new systemic agents have to be performed, among them agents targeting the PD1/PD-L1 axis.

Hyperprogression during anti-PD-1/PD-L1 therapy in patients with recurrent and/or metastatic head and neck squamous cell carcinoma.

BACKGROUND: Pembrolizumab and nivolumab are immune checkpoint inhibitors targeting PD-1 that have recently been approved in pretreated recurrent and/or metastatic head and neck squamous cell carcinoma (R/M HNSCC) patients. In the clinic, some patients seem not only not to benefit from anti-PD-L1/PD-1 agents but rather to experience an acceleration of tumor growth kinetics (TGK). PATIENTS AND METHODS: We retrospectively compared TGK on immunotherapy and TGK on last treatment in patients with R/M HNSCC treated with PD-1/PD-L1 inhibitors in four French centers. The TGK ratio (TGKR, ratio of the slope of tumor growth before treatment and the slope of tumor growth on treatment) was calculated. Hyperprogression was defined as a TGKR ≥ 2. RESULTS: From September 2012 to September 2015, 34 patients were identified. Patterns of recurrence included exclusive loco-regional recurrence in 14 patients, exclusive distant metastases in 11 patients, and both in 9 patients. No pseudo-progression was observed. Hyperprogression was observed in 10 patients (29%), including 9 patients with at least a locoregional recurrence, and only 1 patient with exclusively distant metastases. Hyperprogression significantly correlated with a regional recurrence (TGKR ≥ 2: 90% versus TGKR < 2: 37%, P = 0.008), but not with local or distant recurrence. Hyperprogression was associated with a shorter progression-free survival (PFS) according to RECIST (P = 0.003) and irRECIST (P = 0.02), but not with overall survival (P = 0.77). CONCLUSIONS: Hyperprogression was observed in 29% of patients with R/M HNSCC treated with anti-PD-L1/PD-1 agents and correlated with a shorter PFS. It occurred in 39% of patients with at least a locoregional recurrence and 9% of patients with exclusively distant metastases. No pseudo-progressions were reported. Mechanisms and causality of hyperprogression should further be assessed through prospective controlled studies.

[Role of radiotherapy in the management of non-Hodgkin lymphomas]. / Place de la radiothérapie dans la prise en charge des lymphomes malins non hodgkiniens.

The purpose of this review was to summarize recent data about lastest retrospective and prospective studies dealing with radiotherapy of non-Hodgkin lymphoma, in order to precise the schedule and the role of this treatment. A systematic review was done by searching studies on the website http://www.pubmed.gov (Medline) using the following keywords: radiotherapy, radiation therapy, non-Hodgkin lymphoma. The management of non-Hodgkin lymphoma varies a lot according to the histological type and stage. The dose of radiotherapy has been studied in only one randomized trial, which concluded that there was no difference between the low dose and the high dose arms. Radiotherapy is a very good option in follicular, cutaneous, digestive or orbital non-Hodgkin lymphoma. A recent post hoc analysis of randomized trials on radiotherapy for high-grade non-Hodgkin lymphoma strongly suggested a benefit of additional radiotherapy after chemotherapy in some situations. Radiotherapy of low-grade non-Hodgkin lymphoma is a very good option, while its use on high-grade non-Hodgkin lymphoma is sometimes recommended but further randomized trials are ongoing to better understand its role.

Impact of tumor HPV status on outcome in patients with recurrent and/or metastatic squamous cell carcinoma of the head and neck receiving chemotherapy with or without cetuximab: retrospective analysis of the phase III EXTREME trial.

BACKGROUND: Tumor human papillomavirus (HPV) status is an important prognostic factor in locoregionally advanced squamous cell carcinoma of the head and neck (SCCHN). Prognostic value in recurrent and/or metastatic (R/M) disease remains to be confirmed. This retrospective analysis of the EXTREME trial, comparing chemotherapy plus cetuximab with chemotherapy first line in R/M SCCHN, investigated efficacy and prognosis according to tumor p16 and HPV status. PATIENTS AND METHODS: Paired tissue samples were used: p16INK4A expression was assessed by immunohistochemistry, and HPV status determined in extracted DNA samples using oligonucleotide hybridization assays. RESULTS: Altogether, 416 of 442 patients had tumor samples available for p16 and HPV: 10% of tumors were p16 positive and 5% were HPV positive. Adding cetuximab to chemotherapy improved survival, irrespective of tumor p16 or HPV status. This pattern remained in a combined analysis of p16 and HPV. p16 positivity and HPV positivity were associated with prolonged survival compared with p16 negativity and HPV negativity. Subgroup analysis of patients with oropharyngeal cancer demonstrated a similar pattern to all evaluable patients. CONCLUSION: The results from this analysis suggest that p16 and HPV status have prognostic value in R/M SCCHN and survival benefits of chemotherapy plus cetuximab over chemotherapy alone are independent of tumor p16 and HPV status.

Cisplatin, 5-fluorouracil, and cetuximab (PFE) with or without cilengitide in recurrent/metastatic squamous cell carcinoma of the head and neck: results of the randomized phase I/II ADVANTAGE trial (phase II part).

BACKGROUND: Recurrent and/or metastatic squamous cell carcinoma of the head and neck (R/M-SCCHN) overexpresses αvß5 integrin. Cilengitide selectively inhibits αvß3 and αvß5 integrins and is investigated as a treatment strategy. PATIENTS AND METHODS: The phase I/II study ADVANTAGE evaluated cilengitide combined with cisplatin, 5-fluorouracil, and cetuximab (PFE) in R/M-SCCHN. The phase II part reported here was an open-label, randomized, controlled trial investigating progression-free survival (PFS). Patients received up to six cycles of PFE alone or combined with cilengitide 2000 mg once (CIL1W) or twice (CIL2W) weekly. Thereafter, patients received maintenance therapy (cilengitide arms: cilengitide plus cetuximab; PFE-alone arm: cetuximab only) until disease progression or unacceptable toxicity. RESULTS: One hundred and eighty-two patients were treated. Median PFS per investigator read was similar for CIL1W + PFE, CIL2W + PFE, and PFE alone (6.4, 5.6, and 5.7 months, respectively). Accordingly, median overall survival and objective response rates were not improved with cilengitide (12.4 months/47%, 10.6 months/27%, and 11.6 months/36%, respectively). No clinically meaningful safety differences were observed between groups. None of the tested biomarkers (expression of integrins, CD31, Ki-67, vascular endothelial growth factor receptor 2, vascular endothelial-cadherin, type IV collagen, epidermal growth factor receptor, or p16 for human papillomavirus) were predictive of outcome. CONCLUSION: Neither of the cilengitide-containing regimens demonstrated a PFS benefit over PFE alone in R/M-SCCHN patients.

Clinical and histological prognostic factors in locally advanced oral cavity cancers treated with primary surgery.

OBJECTIVE: The primary objective of this study was to determine the clinical and pathological prognostic factors in locally advanced oral cavity cancers treated by primary surgery. METHODS: All patients treated by primary surgery with free-flap reconstruction for locally advanced oral cavity squamous cell carcinoma in our institution between 2000 and 2010 were included in this retrospective study. Overall, cause-specific and locoregional disease-free survivals were determined by Kaplan-Meier analyses. Clinical and histological prognostic factors were assessed by univariate (Log Rank tests) and multivariate (Cox models) analyses. RESULTS: A total of 149 patients (102 men and 47 women; mean age=61.3±12.1 years) were included in the study. Five-year overall, cause-specific and locoregional disease-free survivals were 55%, 68% and 71%, respectively. Age, comorbidity and tumour size (histological evaluation) were significantly correlated with overall survival (P<0.05). Age, tumour size, bone invasion and surgical margins were significantly correlated with locoregional disease-free survival (P<0.05). CONCLUSION: The main prognostic factors identified in this study were clinical (age and comorbidity) and histological (pathological tumour size, bone invasion and surgical margins).

[Induction chemotherapy for head and neck epidermoid carcinomas]. / Chimiothérapie d'induction des carcinomes épidermoïdes de la tête et du cou.

The standard treatment for head and neck inoperable squamous cell carcinoma is an association of radiotherapy and platinum. However, only one patient out of three remains alive five years after diagnosis. The interest in induction chemotherapy was renewed by the introduction of taxanes combined with cisplatinum and 5-fluoro-uracile. The triple association taxane-cisplatinum-5-fluoro-uracile yielded improved survival when compared to cisplatinum-5-fluoro-uracile. Wider use of taxane-cisplatinum-5-fluoro-uracile is limited by its toxicity and the lack of randomized comparison with a concomitant chemoradiotherapy scheme including optimal doses of platinum. Until the results of new phase III trials are published, the choice between induction chemotherapy followed by concomitant chemoradiotherapy or concomitant chemoradiotherapy alone has to be made on an individualized basis, taking into account the patient's medical condition, the ability of the medical team to deal with intensive treatment regimens, and the clinical/pathological characteristics of the tumour.

[Six cases of pulmonary MALT lymphoma: a heterogeneous therapeutic management]. / Six cas de lymphomes pulmonaires de type MALT : une prise en charge thérapeutique hétérogène.

Pulmonary mucosa-associated lymphoid tissue lymphomas (PMALT) account for around 1% of lymphomas. Clinical and radiological presentations, and the treatment of six PMALT were collected from 1993 to 2008. All patients received chemotherapy before disease progression. Two patients had a lobectomy and one received thoracic radiotherapy. In 2008, all the patients were alive and three were in remission. A "watch and wait" strategy is widely accepted for stable, asymptomatic patients and patients with low tumour mass. Surgery may be proposed for symptomatic patients who have localised PMALT. When a chemotherapy treatment is to be suggested, chlorambucil-based chemotherapy is preferred. There may be room for rituximab alone or in combination, but this remains to be precisely defined. Several larger studies are currently ongoing to assess the role of monoclonal antibodies and chemotherapy in MALT lymphomas. Subgroup analysis should help us to define the optimal treatment for PMALT.

Management of radiation dermatitis in patients receiving cetuximab and radiotherapy for locally advanced squamous cell carcinoma of the head and neck: proposals for a revised grading system and consensus management guidelines.

BACKGROUND: Radiation dermatitis developing in patients receiving cetuximab concomitantly with radiotherapy for locally advanced squamous cell carcinoma of the head and neck (LA SCCHN) is now recognized to have different pathophysiological and clinical characteristics to the radiation dermatitis associated with radiotherapy or concomitant chemotherapy and radiotherapy. Current grading tools were not designed to grade this type of radiation dermatitis; their use may lead to misclassification of reactions and inappropriate management strategies, potentially compromising cancer treatment. PATIENTS AND METHODS: An advisory board of seven leading European specialists (three medical oncologists, three radiation oncologists and a dermatologist) with extensive experience of the use of cetuximab plus radiotherapy produced consensus guidelines for the grading and management of radiation dermatitis in patients receiving cetuximab plus radiotherapy. RESULTS: Modifications to the current, commonly used National Cancer Institute-Common Terminology Criteria for Adverse Events version 4.3 for grading radiation dermatitis were proposed. Updated management guidelines, building on previously published guidelines from 2008, were also proposed. CONCLUSIONS: The proposed revisions to the grading system and updated management guidelines described here represent important developments toward the more appropriate grading and effective management of radiation dermatitis in patients receiving cetuximab plus radiotherapy for LA SCCHN.

Head and neck free-flap reconstruction in the elderly.

OBJECTIVE: To evaluate the reliability of free-flap head and neck reconstruction in the elderly. MATERIAL AND METHODS: All patients who underwent free-flap head and neck reconstruction in our institution between 2000 and 2010 were included in this retrospective study. In all, 418 patients (301 men and 117 women) were enrolled, including 95 patients aged 70 years or older (mean age=60.2±11.6 years). The impact of age on free-flap failure and local and general complication rates was assessed on univariate and multivariate analysis. RESULTS: Advanced age had no impact on free-flap failure and local complications rate but was correlated with a higher risk of general complications (multivariate analysis: P=0.007). A high level of comorbidity also had a significant impact on the general complications rate (multivariate analysis: P=0.001). Patients who underwent circular total pharyngolaryngectomy showed elevated risk of free-flap failure (P=0.005) and local complications (P=0.001) on multivariate analysis. CONCLUSION: Free-flap reconstruction of the head and neck is safe and reliable in the elderly. Nevertheless, meticulous patient selection, mainly based on the level of comorbidity, is necessary.

[Total pharyngolaryngectomy in the 21st century: indications, oncologic and functional outcomes]. / Les pharyngo-laryngectomies totales au 21ème siècle : indications, résultats carcinologiques et fonctionnels.

INTRODUCTION: The development of laryngeal preservation protocols has considerably modified the indications for total (pharyngo-)laryngectomy (TPL). The objectives of our study are to analyze the current indications for TPL and to evaluate the oncologic and functional outcomes after TPL and their predictive factors. METHODS: All patients who underwent TPL for squamous cell carcinoma of the larynx or hypopharynx, at our institution, between 2000 and 2009, were included in this retrospective study. Predictive factors of oncologic and functional outcomes were assessed in univariate and multivariate analyzes. RESULTS: A total of 130 patients were enrolled in our study including 119 men and 11 women, with a mean age of 65.9 years. TPL was realized for salvage in 65 patients. Extra-laryngeal tumor extension (n = 42) was the main indication for TPL in the 65 remaining patients. Overall survival was 49 and 41% at 3 and 5 years respectively. In multivariate analysis, primary tumor site (hypopharynx in comparison to larynx; p = 0.04) has a significant pejorative impact on overall survival. Oral alimentation (no enteral nutrition) was recovered successfully by 94% of the patients. In multivariate analysis, primary tumor site (hypopharynx) has a significant pejorative impact on functional results (deglutition: p < 0.0001; phonation: p = 0.03). CONCLUSION: Primary tumor site is one of the main predictive factor of oncologic and functional outcomes after TPL.

Acceptance of the 2009 A(H1N1) influenza vaccine among hospital workers in two French cancer centers.

The aim of the study was to determine predictive factors influencing the acceptance of the 2009 A(H1N1) influenza vaccination among hospital workers (HW) in two French cancer centers. A standardized, anonymous, self-administered questionnaire was sent to HW of two cancer centers. The survey response rate was 26.2% (n=506). Main reasons for A(H1N1) vaccination acceptance were "to protect my relatives" (30.3%), "to protect myself" (30.3%). Main reasons for A(H1N1) vaccination refusal were the fear of side effects (43.1%), doubt about the vaccine's efficacy (25.8%). Vaccinated HW were more influenced by the institutional campaign (p<0.001) or colleagues' advice (p<0.001) whereas non-vaccinated HW were influenced by their family physician's advice (p=0.03), personal conviction (p<0.001) or the media (p<0.001). A multivariate analysis revealed age (>35 vs ≤ 35), prior seasonal influenza vaccination, professional category and source of information to be predictive factors of vaccination. Future vaccination campaigns will need to focus on young HW (≤ 35-year old), with no prior influenza vaccination and HW who are in contact with patients and who reported low seasonal influenza vaccination rates.

[New influenza A (H1N1) pandemia and cancer patients: what do we do?]. / Nouvelle pandémie de grippe A (H1N1) : que faire pour les patients atteints d'un cancer ?

The new swine-origin influenza A (H1N1) strain (S-OIV) pandemia may expose immunodepressed cancer patients under chemotherapy to an increased risk of mortality. Here, we put into perspective available antiviral treatments and influenza vaccination efficacy in cancer patients and consider that recommendations for seasonal influenza vaccination for these patients are applicable for the upcoming S-OIV vaccines. We recommend a triple vaccination in cancer patients (seasonal influenza, S-OIV, streptococus pneumoniae), if possible at least two weeks before beginning chemotherapy. In case of an influenza-like illness under chemotherapy, the care will depend on the neutrophilic level. If neutrophil count is under 500 units/mm3, hospital admission is recommended with adapted isolation measures and the prescription of an antiviral treatment with oseltamivir 75 mg twice a day for 5 days, if the onset of symptoms occurred within 48 hours. In case of a sign of severity, antiviral treatment should be started regardless of time of the onset of symptoms. Probabilistic antibiotics should also be introduced. In the absence of neutropenia, home care should be favored, by explaining recommended hygienic measures and by starting an antiviral treatment with the same modalities as described previously. Hospital admission is indicated if a sign of severity is present. Patients under chemotherapy, if not vaccinated, who have had a contact with an infected person should receive a prophylactic antiviral treatment with oseltamivir 75 mg once a day for 10 days.

[Neck dissection following chemoradiation for node positive head and neck carcinomas]. / Place du curage ganglionnaire après chimioradiothérapie dans les carcinomes épidermoïdes des voies aérodigestives supérieures avec atteinte ganglionnaire initiale (nasopharynx exclu).

The optimal timing and extent of neck dissection in the context of chemoradiation for head and neck cancer remains controversial. For some institutions, it is uncertain whether neck dissection should still be performed upfront especially for cystic nodes. For others, neck dissection can be performed after chemoradiation and can be omitted for N1 disease as long as a complete response to chemoradiation is obtained. The question is debated for N2 and N3 disease even after a complete response as the correlation between radiological and clinical assessment and pathology may not be reliable. Response rates are greater than or equal to 60% and isolated neck failures are less than or equal to 10% with current chemoradiation protocols. Some therefore consider that systematic upfront or planned neck dissection would lead to greater than or equal to 50% unnecessary neck dissections for N2-N3 disease. Positron-emission tomography (PET) scanning to assess treatment response and have shown a very high negative predictive value of greater than or equal to 95% when using a standard uptake value of 3 for patients with a negative PET at four months after the completion of therapy. These data may support the practice of observing PET-negative necks. More evidence-based data are awaited to assess the need for neck dissection on PET. Selective neck dissection based on radiological assessment and peroperative findings and not exclusively on initial nodal stage may help to limit morbidity and to improve the quality of life without increasing the risk of neck failure. Adjuvant regional radiation boosts might be discussed on an individual basis for aggressive residual nodal disease with extracapsular spread and uncertain margins but evidence is missing. Medical treatments aiming at reducing the metastatic risk especially for N3 disease are to be evaluated.

Very Late Local Relapse of Ewing's Sarcoma of the Head and Neck treated with Aggressive Multimodal Therapy.

Ewing's sarcoma's relapse rarely occurs more than two years after the initial diagnosis. We report the case of a 26-year-old man with a history of Ewing's sarcoma of the left maxillary sinus at the age of 10 who presented with a very late local relapse, 16 years after the first occurrence of disease. Ultimate control was achieved after multimodal therapy including surgery, high-dose chemotherapy, and radiotherapy. This report indicates that local relapses of Ewing's sarcoma can be treated with curative intent in selected cases.

A comparison between distal and proximal port device insertion in head and neck cancer.

AIM: To compare technical feasibility and complications of radiologically arm port device implantation using arm venography exclusively (API-Group B) with chest port placement using cephalic vein cutdown (CVC-Group A), in advanced consecutive head and neck cancer patients (HNP). METHODS: Port device placement was attempted in 225 consecutive HNP. Decision for inclusion in Group A or B was made first by the availability of the surgeon/radiologist to perform the procedure, second by contraindications of each technique. Patient transfer from one group to the other was recorded as well as technical feasibility, complications and device specific duration in this retrospective study. RESULTS: Technical success was statistically higher in Arm Port Group (99.1%) compared to Chest Port Group (75.2%). Device specific duration rate of the whole population was 53% (95%CI) [0.47-0.60] at 6 months, 44.1% (95%CI) [24.4-37.8] at 12 months and 8% (95%CI) [4.4-14.5] at 24 months. Median follow-up was 5.55 months (range: 0.032-9.6] in Group A versus 5.90 months [range: 0.06-27.6] (p=ns) in Group B. Complication rate was 15.9% in Group A versus 8.9% in Group B corresponding to a complication rate per patient-implantation-days of 0.66/1000 patient-days (A) versus 0.42/1000 patient-days (B). Premature port device explantation rate was 4.4% (A) versus 5.4% (B). Axillary and subclavian venous thrombosis was the main complication and occurred in 12 Group A patients and three Group B patients. Venous thrombosis rate was 0.37/1000 patient-days (A) and 0.13/1000 patient-days (B) (p=0.03). CONCLUSIONS: A few data exist about device insertion in HNP in whom venous cervical access is contraindicated. This comparative study demonstrates that both implantation techniques are safe and effective. The higher technical success rate with 0% heavy sedation, the lower venous thrombosis rate in the API group, and the 5.3% (A-B) patient transfer rate argue in favour of arm port placement in HNP. Indications for API include patients with an ipsilateral major pectoralis-myocutaneous flap, with radiodermatitis, tumour recurrence in the neck and upper chest, or with respiratory impairment.
