Pretreatment weight status and weight loss among head and neck cancer patients receiving definitive concurrent chemoradiation therapy: implications for nutrition integrated treatment pathways.

PURPOSE: The purpose was to examine the effect of pretreatment weight status on loco-regional progression for patients with squamous cell carcinoma of the head and neck (SCCHN) after receiving definitive concurrent chemoradiation therapy (CCRT). METHODS: In an expanded cohort of 140 patients, we retrospectively reviewed weight status and loco-regional progression of SCCHN patients treated with CCRT between 2004 and 2010. RESULTS: Pretreatment ideal body weight percentage (IBW%) was statistically significantly different for patients with disease progression than for those without progression (p = 0.02) but was not an independent predictor of progression. Median pretreatment IBW% was 118 (72-193) for the progression-free group and was 101.5 (73-163) for the group with progression. Both groups suffered clinically severe weight loss of approximately 9 % from baseline to end treatment. CONCLUSIONS: Pretreatment weight status, a very crude indicator of nutrition status, may have prognostic value in patients with SCCHN undergoing definitive CCRT. Inadequate nutritional status in these patients has been associated with poor clinical outcomes and decreased quality of life. Based on this report and others, the best next steps include routine validated malnutrition screening and the testing of evidence-based nutrition care protocols with the goals of minimizing weight loss and improvement of quality of life.

Pectoralis major myocutaneous flap for reconstruction of circumferential pharyngeal defects.

BACKGROUND: A 270-degree partially tubed pectoralis major myocutaneous flap (PMMF) is an excellent option for total circumferential pharyngoesophageal defects in patients who are not candidates for more complex reconstructions. METHODS: Patients undergoing circumferential pharyngoesophageal reconstruction with partially tubed PMMF were reviewed. End points were stricture, fistula, resumption of oral intake, perioperative death, and recurrence. RESULTS: Eleven patients underwent 270-degree PMMF for reconstruction: 6 (55%) were men and 5 (45%) were women (mean, 62 years; range, 42-78 years). Three patients (27%) developed fistulas and 2 (18%) developed stenosis. Ten patients (91%) were able to resume adequate nutrition via oral intake. There were no perioperative deaths. CONCLUSIONS: Patients with severe comorbidities, metastatic disease, a lack of donor vessels, or a potentially hostile abdomen may not be ideal candidates for free tissue transfer. For these patients, partially tubed PMMF using the prevertebral fascia provides a reliable alternative for reconstruction with excellent functional results.

Idiosyncrasies of scalp melanoma.

OBJECTIVES/HYPOTHESIS: Examine the accuracy of sentinel lymph node biopsy (SNB) in scalp melanoma (SM), patterns of nodal metastases, patient outcomes, and the utility of immunohistochemistry (IHC) in SNB evaluation. STUDY DESIGN: Retrospective. METHODS: There were 22 patients, 4 females and 18 males. Sentinel lymph nodes (SLN) were localized via preoperative lymphoscintigraphy, intraoperative gamma probe, and Lymphazurin injection. SLNs were stained with hematoxylin-eosin, S-100, HMB-45, Melan-A, micropthalmia transcription factor, and tyrosinase. SLNs were grouped into cervical (levels 1-5) and extracervical (parotid, suboccipital, retroauricular) regions. RESULTS: There were 13 posterior and 9 anterior SMs. The first SNB were mapped to the extracervical regions in 77% of posterior and 78% of anterior lesions. SLN number ranged from 1 to 5. Ten patients had positive SLNs (PSLN). Forty percent of the PSLN group had SLNs mapped in both cervical and extracervical sites. Six underwent completion lymphadenectomy, with no additional positive nodes identified. No significant difference between PSLN and negative sentinel node (NSLN) patients was seen when compared by SLN number, Breslow's thickness, tumor ulceration, and clinical outcomes. Mean follow-up was 35 months. One patient died of disease. One isolated regional recurrence occurred. Sixty percent of PSLN and 92% of NSLN patients were recurrence free at last follow-up. One distant metastasis occurred in the NSLN group, and one local, one regional, and two patients with distant metastases were in the PSLN group at the time of last follow-up. Additional IHC did not detect other metastases in the NSLN group. CONCLUSIONS: SM is aggressive, as demonstrated by the high rate of SLN metastases, and there were no significant histopathologic factors in the primary tumor that predicted the presence of SLN metastases. SNB was accurate. The majority of first SLNs were localized in extracervical basins.

Comparative genomic instabilities of thyroid and colon cancers.

OBJECTIVES: To assess the forms and extent of genomic instability in thyroid cancers and colorectal neoplasms and to determine if such measurements could explain the generally excellent prognosis of thyroid malignant neoplasms compared with colon carcinoma. DESIGN: Tumor genome analyses. Genomic instability was measured by the following 4 methods, listed in ascending order based on the size of events detected: inter-simple sequence repeat polymerase chain reaction (ISSR-PCR), fractional allelic loss (FAL) analysis, array-based comparative genomic hybridization (aCGH), and spectral karyotyping (SKY). RESULTS: The genomic instability index of 32 thyroid carcinomas, 59 colon carcinomas, and 11 colon polyps was determined by ISSR-PCR; no difference was seen among the 3 groups by this method. Fractional allelic loss rates were comparable in thyroid cancers and colon polyps and lower than FAL rates in colorectal cancers. Indolent papillary thyroid carcinomas were essentially diploid with no large-scale alterations in chromosome number or structure when evaluated by aCGH or SKY. In anaplastic thyroid cancers, aCGH revealed abundant chromosome alterations. Colorectal carcinomas showed extensive copy number changes and chromosomal rearrangements when analyzed by aCGH and SKY. CONCLUSIONS: Genomic alterations in papillary thyroid carcinoma, such as in benign colon polyps, are principally smaller events detected by ISSR-PCR. With the more aggressive tumor types (ie, anaplastic thyroid and colorectal carcinomas), larger events detected by FAL analysis, aCGH, and SKY were revealed. We hypothesize that mutations caused by smaller genomic alterations enable thyroid cells to achieve a minimal malignant phenotype. Mutations for aggressive biological behavior appear with larger genomic events.

Intraparotid sentinel lymph node biopsy for head and neck melanoma.

OBJECTIVE: The objective of this retrospective clinical review was to assess the safety and accuracy of intraparotid sentinel node biopsy in patients with melanoma. SETTING: This study was conducted at a tertiary referral center. PATIENTS: Twenty-eight patients with cutaneous melanoma of the head and neck undergoing sentinel lymph node (SLN) biopsy in which the radionuclide localized to the parotid gland on preoperative lymphoscintigraphy were studied. METHODS: All patients underwent wide local excision of the tumor and intraparotid sentinel node biopsy using intraoperative gamma probe localization. RESULTS: There were 25 men and 3 women ranging in age from 34 to 81 years. The primary site was on the auricle in 14 patients: temple, 4; forehead, 5; cheek, 3; and on the neck in 2 patients, respectively. The mean Breslow thickness was 2.3 mm (range, 0.9-7.0 mm). In 27 of 28 patients, an intraparotid SLN was identified. In one patient, final pathology did not reveal lymphoid tissue despite a high count in the parotid tissue excised. Median number of SLN per patient was two. Six patients had microscopic metastases in the SLN. In two of these patients, additional microscopic lymph node metastases were found in the neck after subsequent formal lymphadenectomy. The pathologic staging for the group (n = 14) was: stage 1B, 4; 2A, 4; stage 2B, 3; and stage 3B, 3 patients, respectively. All patients are alive and without evidence of disease (mean follow up, 31 months). There were no surgical complications, specifically no patient experienced temporary or permanent facial paralysis. CONCLUSION: Intraparotid SLN biopsy for staging cutaneous head and neck melanoma is a reliable, accurate, and safe procedure.

Chemoprevention of head and neck cancer with aspirin: a case-control study.

OBJECTIVE: To evaluate the chemopreventive potential of aspirin against head and neck cancer. DESIGN: Hospital-based case-control study. SETTING: National Cancer Institute-designated comprehensive cancer center. Patients Individuals who received medical services at the Roswell Park Cancer Institute, Buffalo, NY, between 1982 and 1998 and who completed a comprehensive epidemiologic questionnaire. MAIN OUTCOME MEASURE: Aspirin use among 529 patients with head and neck cancer and 529 hospital-based control subjects matched by age, sex, and smoking status. RESULTS: Aspirin use was associated with a 25% reduction in the risk of head and neck cancer (adjusted odds ratio, 0.75; 95% confidence interval, 0.58-0.96). Consistent risk reductions were also noted in association with frequent and prolonged aspirin use. Further, a consistently decreasing trend in risk was noted with increasing duration of aspirin use (P(trend) = .005). Risk reduction was observed across all 5 primary tumor sites, with cancers of the oral cavity and oropharynx exhibiting greater risk reduction. When analyzed by smoking and alcohol exposure levels, participants moderately exposed to either showed a statistically significant 33% risk reduction (adjusted odds ratio, 0.67; 95% confidence interval, 0.50-0.91), whereas participants exposed to both heavy smoking and alcohol use did not benefit from the protective effect of aspirin. The reduction in risk was relatively more significant in women. CONCLUSIONS: Aspirin use is associated with reduced risk of head and neck cancer. This effect is more pronounced in individuals with low to moderate exposure to cigarette smoke or alcohol consumption.

Photodynamic therapy with 3-(1'-hexyloxyethyl) pyropheophorbide-a for early-stage cancer of the larynx: Phase Ib study.

BACKGROUND: The purpose of this study was for us to report results regarding the safety of 3-(1'-hexyloxyethyl) pyropheophorbide-a (HPPH) mediated photodynamic therapy (PDT) in early laryngeal disease, and offer preliminary information on treatment responses. METHODS: A single-institution, phase Ib, open label, noncomparative study of HPPH-PDT in patients with high-risk dysplasia, carcinoma in situ, and T1 squamous cell carcinoma (SCC) of the larynx. The primary outcomes were safety and maximum tolerated dose (MTD), and the secondary outcome was response. RESULTS: Twenty-nine patients and 30 lesions were treated. The most common adverse event (AE) was transient hoarseness of voice. Severe edema, requiring tracheostomy, was the most serious AE, which occurred in 2 patients within several hours of therapy. The MTD was 100 J/cm(2) . Patients with T1 SCC seemed to have good complete response rate (82%) to HPPH-PDT at MTD. CONCLUSION: HPPH-PDT can be safely used to treat early-stage laryngeal cancer, with potential efficacy. © 2015 The Authors Head & Neck Published by Wiley Periodicals, Inc.

Development of head and neck squamous cell carcinoma is associated with altered cytokine responsiveness.

Growth of head and neck squamous cell carcinoma (HNSCC) is generally associated with an inflammatory component. It is hypothesized that these tumor cells develop mechanisms to evade the growth inhibitory effects of cytokines that are present in the tumor microenvironment. This study determined the changes in responsiveness to inflammatory cytokines that accompany the transition of normal to transformed epithelial cells. Paired primary cultures of normal epithelial cells (NEC) and SCC cells were established from 16 patients. Receptor-mediated activation of signal transducer and activator of transcription and extracellular signal-regulated kinase pathways in response to cytokine treatments was identified by immunoblot analysis. Thymidine incorporation determined the impact of the cytokines on DNA synthesis. HNNEC and HNSCC displayed a prominent signaling in response to oncostatin M, interleukin-6, IFN-gamma, and epidermal growth factor. Untreated HNSCC showed an elevated level of phosphorylated signal transducer and activator of transcription 3 and extracellular signal-regulated kinase (P < 0.001) compared with HNNEC, suggesting constitutively activated pathways. Moreover, HNSCC cells phosphorylated significantly more signal transducer and activator of transcription 1 in response to oncostatin M (P = 0.002) and IFN-gamma (P = 0.018) treatments. DNA synthesis of SCC cells was less inhibited by cytokines produced by endotoxin-stimulated macrophages (P = 0.016) than that of NEC. Low-dose oncostatin M slightly enhanced proliferation of SCC, whereas that of NEC was suppressed (P = 0.016). This study identified significant alterations in signal transduction pathways engaged by cytokines and which are associated with loss of growth inhibition of HNSCC. Increased signal transducer and activator of transcription phosphorylation, along with constitutively phosphorylated extracellular signal-regulated kinase in HNSCC, suggest that these pathways as molecular markers are important in the malignant transformation process and are potential targets for treatment.

Is there disparity in the care of minority patients with upper aerodigestive tract malignancy?

The data presently available indicate that there is unequal (disparate) care in patients with head and neck cancer. The reasons for this are likely multifactorial and require further study. Complicating such work is the need for subgroup analysis. For example, Hispanics are not a homogeneous ethnic group; hence, differences in social perception, cultural mores, and available medical resources can be demonstrated that can directly impact care and outcome. Appropriate epidemiologic studies are needed with more underserved minority patients to analyze these differences further and to address such differences.

Molecular prognosticators and genomic instability in papillary thyroid cancer.

OBJECTIVES/HYPOTHESIS: Tumor progression has been attributed to the accumulation of DNA damage concurrent with selection of advantageous mutations; this DNA damage may result from failure to maintain genomic integrity or from susceptibility to carcinogens. Glutathione S-transferases (GSTs), enzymes that metabolize many carcinogens, may play a role in preserving genome integrity. The objectives of this study are to assess the relationship of GST genotypes with prognosis, clinicopathologic parameters, and genomic instability in papillary thyroid cancer. STUDY DESIGN: Prospective analysis. METHODS: GSTM1 and GSTT1 genotypes of 35 matched normal and papillary thyroid cancer specimens were determined by polymerase chain reaction (PCR) using primers specific for the coding sequences of each gene. Genomic instability was measured by intersimple sequence repeat PCR for each tumor/normal pair and compared with the GAMES prognostic scoring system and clinicopathologic parameters including age, extrathyroidal extension, tumor grade, size, stage metastasis, sex, and smoking history. RESULTS: GSTM1 and GSTT1 null genotypes were found in the normal tissues of 46% and 45%, respectively. No gene losses were detected in the tumor specimens. A significant association between the GSTM1 null genotype and increased risk of recurrence and death was observed. Elevated GII correlated with smoking and tumor stage but not with GST genotype. CONCLUSION: The association of GSTM1 null genotype with intermediate and high risk GAMES categories suggests that GSTM1 provides some protection against disease progression. However, this protection does not confer resistance to disease onset. GST genotyping may be a useful adjunct prognosticator with GAMES.

Advanced soft palate cancer: the clinical importance of the parapharyngeal space.

OBJECTIVE: To identify the incidence of parapharyngeal space (PPS) recurrences and how they impact survival in advanced-stage soft-palate carcinoma patients. STUDY DESIGN AND SETTING: One hundred thirty-seven patients' charts were reviewed from 1971 to 1996. Inclusion criteria were patients who received a per-oral resection, discontinuous neck dissection, and postoperative adjuvant radiation therapy; 15 patients met criteria for inclusion. The incidence of PPS recurrences, regional failure, and survival were endpoints that were analyzed. RESULTS: There were no local failures in our study. Regional failures excluding the PPS (levels I-V) were 27%, and 40% occurred within the PPS. Cervical adenopathy was associated with 83% of the PPS recurrences. Median survival for PPS recurrences was 26 months, compared with 67 months for levels I-V recurrences (n = ns). CONCLUSIONS: The incidence of PPS recurrences is substantial in advanced-stage soft-palate cancer. PPS recurrences negatively impact survival; without effective salvage techniques for these recurrences or effective adjuvant therapy, poor patient outcomes can be expected.

Image-guided Interstitial Photodynamic Therapy for Squamous Cell Carcinomas: Preclinical investigation.

OBJECTIVE: Photodynamic therapy (PDT) is a clinically approved minimally invasive treatment for cancer. In this preclinical study, using an imaging-guided approach, we examined the potential utility of PDT in the management of bulky squamous cell carcinomas (SCCs). METHODS: To mimic bulky oropharyngeal cancers seen in the clinical setting, intramuscular SCCs were established in six-to-eight week old female C3H mice. Animals were injected with the photosensitizer, 2-[hexyloxyethyl]-2-devinyl pyropheophorbide-a (HPPH; 0.4 µmol/kg, i.v.) and tumors were illuminated 24 hours post injection with 665 nm light. PDT as a single treatment modality was administered by surface illumination or by interstitial placement of fibers (iPDT). Magnetic resonance imaging was used to guide treatment and assess tumor response to PDT along with correlative histopathologic assessment. RESULTS: Interstitial HPPH-PDT resulted in a marked change on T2 maps 24 hours post treatment compared to untreated controls or transcutaneous illumination. Corresponding apparent diffusion coefficient maps also showed hyperintense areas in tumors following iPDT suggestive of effective photodynamic cell kill. Histologic sections (H&E) confirmed presence of extensive tumor necrosis following iPDT. CONCLUSIONS: These results highlight the potential utility of PDT in the treatment of bulky oropharyngeal cancers. The findings of our study also demonstrate the utility of MRI as a non-invasive tool for mapping of early tissue response to PDT.

Sentinel lymph node biopsy in staging of differentiated thyroid cancer: a critical review.

Sentinel lymph node biopsy has recently been utilized to map tumor lymphatics in patients with differentiated thyroid carcinoma. Currently, controversy centers around the feasibility and future role of this technique in the management of differentiated thyroid cancer patients. A review of the current literature in which sentinel lymph node biopsy was performed on patients with a diagnosis of differentiated thyroid cancer was undertaken. Sentinel lymph node biopsy has been carried out on thyroid cancer patients utilizing a vital dye technique, a radiotracer technique, and a combination of both techniques. In the current literature the average rate of sentinel node identification is 91% (range 66-100%) and when identified, the sentinel node accurately predicts the disease status of the neck in most patients (range 80-100%). Limitations to carrying out the sentinel node biopsy on thyroid cancer patients include staining of parathyroid glands, identification of lymph nodes draining into the mediastinum, and the 'shine through' effect. Sentinel lymph node biopsy is technically feasible, but for a disease in which nodal metastases are of debatable prognostic value, the clinical utility of sentinel lymph node biopsy in the management of patients with differentiated thyroid cancer appears less than promising.

Bronchogenic cyst presenting as a symptomatic neck mass in an adult: case report and review of the literature.

We report the unusual clinical manifestation and subsequent management of a symptomatic congenital bronchogenic cyst that connected to the trachea and presented in the neck of an adult. The embryology, clinical presentation, diagnostic evaluation, and management options of this rare aberration are discussed.

Anaplastic thyroid cancer evolved from papillary carcinoma: demonstration of anaplastic transformation by means of the inter-simple sequence repeat polymerase chain reaction.

BACKGROUND: In thyroid tumors, the coexistence of well- and poorly differentiated tumor types has led to the hypothesis that poorly differentiated thyroid tumors develop from well-differentiated thyroid tumors. By evaluating the genomic instability of histologically distinct but coexisting tumor foci, this study aimed to develop an improved understanding of thyroid tumorigenesis and tumor evolution. DESIGN: Laser capture microdissection (LCM) was carried out on archival formalin-fixed, paraffin-embedded sections from a tumor containing foci of classic papillary thyroid cancer and anaplastic thyroid cancer. DNA was extracted from each microdissected tumor focus. In addition, cryopreserved bulk normal and neoplastic thyroid tissue underwent DNA extraction. All DNA samples were subsequently evaluated for genomic instability by means of inter-simple sequence repeat polymerase chain reaction. RESULTS: The LCM DNA from each archival paraffin-embedded tumor focus demonstrated unique patterns of banding as compared with the cryopreserved tumor and normal tissue DNA. Thus, intratumoral variability in genomic instability was observed. Comparison of inter-simple sequence repeat polymerase chain reaction patterns of LCM DNA from adjacent foci of papillary and anaplastic tumors showed conserved genome alterations. CONCLUSIONS: At the genome level, thyroid tumors may be highly heterogeneous. The intratumoral histologic heterogeneity observed in thyroid neoplasms reflects genetically heterogeneous underlying tumor cell populations that are demonstrated by the observed differences in their rates and extents of genomic instability. The conserved genomic alterations in the microdissected papillary and anaplastic foci suggest intratumoral evolution, with transformation of a preexisting papillary tumor to anaplastic carcinoma.

Neck dissection: current concepts and future directions.

For individuals diagnosed with head and neck cancer, neck dissection may be performed for therapy or disease staging. The classification of neck dissection and the definition of precise anatomic landmarks have allowed for this operation, and its many variations, to become standardized world-wide. SLNBX shows promise in its ability to accurately stage NO head and neck cancer and may allow patients with no micro metastatic disease to avoid neck dissection. Before this technique becomes adopted into routine clinical practice, however, it must first be prospectively scrutinized in large patient populations. Regardless of the future role of SLNBX in the management of head and neck cancer, currently it is only through a complete understanding of the clinical, theoretic, and technical aspects of neck dis-section that surgeons may benefit individual patients and the head and neck cancer patient population as a whole.

Current concepts in the management of a second malignancy of the lung in patients with head and neck cancer.

Simultaneous, synchronous, and metachronous presentation of lung malignancies when treating head and neck squamous cell cancers is one of the most difficult challenges in head and neck surgery. However, good (> 40%) 5-year survival can be obtained when proper screening techniques, patient selection, and therapy are combined. Because of the complexity of the head and neck resection and reconstruction and the multiple surgical and medical services used to diagnose and treat this clinical entity, a comprehensive review of the current literature is provided. The clinically pertinent meanings of simultaneous, synchronous, and metachronous second malignancy of the lung are presented. A review of the current literature is presented that divides second lung malignancy into two groups: second primary and metastasis. The incidence of a second lung malignancy is identified. The tools used in the screening of high-risk patients and the role of the new diagnostic studies such as positron emission tomography and positron emission tomography CT scans are reviewed. Finally, the current literature on patient selection and surgical therapy is used to put forth a clinical pathway followed at the authors' institution for the treatment of these patients.

Adenoid cystic carcinoma of the paranasal sinuses or nasal cavity: a 40-year review of 35 cases.

We retrospectively reviewed 35 cases of adenoid cystic carcinoma that had originated in the minor salivary glands of the paranasal sinuses or nasal cavity. All patients had been seen at two tertiary-care referral centers in western New York State between 1960 and 2000. Twenty patients had been treated with surgery and adjuvant radiotherapy, 10 patients with surgery alone, three with radiotherapy alone, and two with concurrent radiotherapy and chemotherapy. During the study, 22 patients developed recurrent disease--11 locally; three distantly; seven locally and distantly; and one locally, regionally, and distantly. At the conclusion of the study, 14 patients were alive and disease-free, and eight were alive with disease; 10 patients had died with disease, and three had died of other causes with no evidence of disease. Adenoid cystic carcinoma of the paranasal sinuses or nasal cavity is an aggressive neoplasm that results in a high incidence of both local recurrence and distant metastasis, regardless of treatment modality. Most cases are ultimately fatal, although long disease-free intervals have been observed. A combination of surgery and radiotherapy offers these patients the best chance for disease control.

Parathyroid carcinoma: a multicenter review of clinicopathologic features and treatment outcomes.

We conducted a retrospective study of 13 patients with parathyroid carcinoma to assess their clinical characteristics and surgical outcomes. Study parameters included patient demographics, survival, treatment response, and recurrence. We found that all patients who had undergone local tumor excision developed a recurrence, compared with only 33% of those available for follow-up after en bloc tumor resection. Based on these findings, we recommend en bloc tumor resection as the initial treatment of choice for patients diagnosed with parathyroid carcinoma.

Survival differences between organ preservation surgery and definitive radiotherapy in early supraglottic squamous cell carcinoma.

OBJECTIVE: Single-modality treatment, either with organ preservation surgery (OPS) or definitive radiation (RT), is the treatment of choice for patients with early supraglottic squamous cell carcinoma (SGC). However, studies comparing the effectiveness of these 2 techniques are lacking. This study compares the survival outcomes in early SGC patients treated with OPS versus RT. STUDY DESIGN: Secondary data analysis. SETTING: Surveillance, Epidemiology and End Results database. SUBJECTS AND METHODS: This study included adult patients with early-stage (T1N0, T2N0) SGC undergoing single-modality treatment with either OPS (with or without neck dissection [ND]) or RT between 1988 and 2008. Survival analysis was used to compare the overall survival (OS) and disease-specific survival (DSS) between patients treated with OPS+ND, OPS alone, and RT. RESULTS: A total of 2631 T1/T2 N0 SGC patients were identified, of whom 167 (6%) were treated with OPS+ND, 186 (7%) with OPS only, and 2278 patients (87%) with definitive RT only. In stage I (T1N0) SGC patients, a significantly better 5-year DSS was noted for both OPS+ND (81% vs 68%, hazard ratio [HR] = 0.61, P = .03) and OPS only (82% vs 68%, HR = 0.70, P = .05) when compared with definitive RT. For stage II (T2N0) patients, only OPS+ND resulted in a significantly better 5-year DSS (86% vs 60%, HR = 0.31, P < .001) when compared with patients treated with RT. CONCLUSIONS: Patients with early SGC who underwent OPS+ND had better OS and DSS than patients undergoing RT alone. OPS+ND may be considered a viable and preferred treatment option in these patients.
