Abstract
Patterns of tumour spread are examined in 160 patients with squamous carcinomas of the head and neck with reference to perineural infiltration, direct invasion of bone and ossified cartilage, and lymph node metastases in the previously irradiated neck. Perineural spread is comparatively common in large (T3, T4) tumours; it may be apparent early in the disease; it is often detectable clinically; and it is an adverse prognostic feature which may modify clinical management. Direct bone invasion is described with particular reference to tumours of the oral cavity. Most bone destruction is mediated by osteoclasts which appear to be stimulated by materials such as prostaglandins released in the vicinity of the tumour. The numbers of involved lymph nodes in surgical dissections from the irradiated neck are usually few and restricted to the submandibular and jugular groups; nodes in the posterior triangle are infrequently involved by metastatic carcinoma. Transcapsular spread and keratin granulomas are common. The scope of modified neck dissections in this group of patients is discussed.

Influence of formalin fixation on tissue dimensions in palatal tonsils. Pathol Res Pract 2013; 210:59-61.

Abstract
AIM To investigate the change of tissue dimensions after formalin fixation, and to determine the optimal time of fixation. HYPOTHESIS Formalin fixation may lead to shrinkage in tissue dimensions and may thus alter tumor stages. BACKGROUND It is often observed in tumor surgery that the dimensions in vivo seem larger than after resection, and tissue appears to shrink further after formalin fixation. This might alter dimensions and assessment of spread of the tumor and thus lead to a lesser tumor classification and stage. In cases where the decision for adjuvant chemoradiation is based upon the stage, it may thus be of relevance for the patient to evaluate the pathologic and not the in vivo dimensions of the tumor. MATERIAL AND METHODS In order to obtain comparable tissues, we investigated 100 palatal tonsils after cold steel dissection tonsillectomy for chronic tonsillitis. There were four time points investigated: directly after excision in the operating room and after four, 24 and 72 h of fixation in formaldehyde (4% Formaldehyde in phosphate buffer pH 7.4). The tissue was measured in the following dimensions: volume (ml), weight (g) and length, broadness and width (mm). RESULTS The tissue size did not change significantly in dimensions except for an increase in length. The time of fixation did not influence the size. DISCUSSION Formalin fixation does not significantly influence the tissue dimensions of palatal tonsils in comparison to direct ex vivo measurements. A minimal time of fixation of 20 h is required in order to stop all degenerative processes; however, longer fixation does not change the dimensions of the specimen. CONCLUSION The null hypothesis has to be withdrawn that tissue dimensions are altered by formalin fixation. Thus, the histopathological measurements do not influence TNM staging.

Abstract
Extracapsular extension in squamous cell carcinoma nodal metastases usually predicts worse outcome. However, there are no standard histologic grading criteria for extracapsular extension, and there have been few studies on oropharyngeal squamous cell carcinoma alone. We studied the extent of extracapsular extension utilizing a novel grading system and correlated grades with outcomes while controlling for p16 status. A cohort of surgically treated oropharyngeal squamous cell carcinoma cases were reviewed and metastases graded as 0 (within substance of node), 1 (filling subcapsular sinus with thickened capsule/pseudocapsule, but no irregular peripheral extension), 2 (≤1 mm beyond capsule), 3 (>1 mm beyond capsule), or 4 (no residual nodal tissue or architecture; 'soft tissue metastasis'). There were 101 cases, for which p16 was positive in 90 (89%). Extracapsular extension grades did not correlate with nodal size (P=0.28) or p16 status (P=0.8). In follow up, 10 patients (10%) had disease recurrence with only 3 of 64 (5%) grade 0-3 cases and 7 of 37 (19%) with grade 4 recurring (P=0.04). Grade 4 extracapsular extension was associated with poorer survival (P<0.01). However, grade 4 extracapsular extension correlated with higher T-stage (P=0.02), and in multivariate analysis, was not significantly associated with poorer overall (P=0.14) disease-free (P=0.2), or disease-specific survival (P=0.09). The impact of extracapsular extension in nodal metastases is limited in oropharyngeal squamous cell carcinoma. Only extracapsular extension grade 4 associates with poorer outcomes, but not independently of T-stage and other variables.

Abstract
Accumulated evidence indicates that cytotoxic function of immune effectors is largely suppressed in the tumor microenvironment by a number of distinct effectors and their secreted factors. The aims of this review are to provide a rationale and a potential mechanism for immunosuppression in cancer and to demonstrate the significance of such immunosuppression in cellular differentiation and progression of cancer. To that end, we have recently shown that NK cells mediate significant cytotoxicity against primary oral squamous carcinoma stem cells (OSCSCs) as compared to their more differentiated oral squamous carcinoma cells (OSCCs). In addition, human embryonic stem cells (hESCs), Mesenchymal Stem Cells (hMSCs), dental pulp stem cells (hDPSCs) and induced pluripotent stem cells (hiPSCs) were all significantly more susceptible to NK cell mediated cytotoxicity than their differentiated counterparts or parental cells from which they were derived. We have also reported that inhibition of differentiation or reversion of cells to a less-differentiated phenotype by blocking NFκB or targeted knock down of COX2 in primary monocytes in vivo significantly augmented NK cell function. Total population of monocytes and those depleted of CD16(+) subsets were able to substantially prevent NK cell mediated lysis of OSCSCs, MSCs and DPSCs. Taken together, our results suggest that stem cells are significant targets of the NK cell cytotoxicity. The concept of split anergy in NK cells and its contribution to tissue repair and regeneration and in tumor resistance and progression will be discussed in this review.

Abstract
BACKGROUND Transoral CO(2) laser microsurgery (TLM) resection of laryngeal-hypopharyngeal squamous cell carcinomas has become a standard procedure. The objective was to evaluate whether there is a relationship between TLM and a higher incidence of distant metastases. METHODS We conducted a retrospective analysis of 340 consecutive patients with laryngeal or hypopharyngeal squamous cell carcinoma treated with TLM. RESULTS Distant metastases occurred in 24 of 340 (7.1%) patients. The mean time of distant metastases diagnosis was 19.1 months (range, 1-41) postsurgery. Univariate study demonstrated an association with alcoholism (p = .008), tumor site (p<.001), grade of differentiation (p = .032), stage (p<.001), tumor classification (T; p = .001), node involvement (N; p<.001), extracapsular node spread (p<.001), and positive surgical margin (p = .004). In multivariate logistic regression analysis, location (sinus piriform: OR = 15.37, p = .025), node involvement (N2: OR = 7.36, p = .003; N3: OR = 19.28, p = .027), and the affected surgical margin (OR 5.32; p = .005) predicted an increased likelihood of distant metastases. CONCLUSIONS Development of distant metastases after TLM in patients with squamous cell carcinoma depends mainly on the tumor site, the presence of metastatic lymph node disease, and the margin status after resection.

Abstract
Mounting effective anti-tumor immune responses against tumors by both the innate and adaptive immune effectors is important for the clearance of tumors. However, accumulated evidence indicates that immune responses that should otherwise suppress or eliminate transformed cells are themselves suppressed by the function of tumor cells in a variety of cancer patients, including those with oral cancers. Signaling abnormalities, spontaneous apoptosis, and reduced proliferation and function of circulating natural killer cells (NK), T-cells, dendritic cells (DC), and tumor-infiltrating lymphocytes (TILs) have been documented previously in oral cancer patients. Several mechanisms have been proposed for the functional deficiencies of tumor-associated immune cells in oral cancer patients. Both soluble factors and contact-mediated immunosuppression by the tumor cells have been implicated in the inhibition of immune cell function and the progression of tumors. More recently, elevated levels and function of key transcription factors in tumor cells, particularly NFkappaB and STAT3, have been shown to mediate immune suppression in the tumor microenvironment. This review will focus on these emerging mechanisms of immunosuppression in oral cancers.

Abstract
The prognostic significance of extracapsular spread of cervical metastases in oral cancer is still controversial. To investigate the importance of extent of extracapsular spread; the relationship between extracapsular spread and both traditional measures of metastatic disease and clinical/histological features of the primary tumour, and to determine their relative prognostic significance. The survival of 173 patients undergoing radical surgery and simultaneous neck dissection for oral/oropharyngeal squamous cell carcinoma with histologically confirmed nodal metastasis and followed for 2.2-12.3 years is reported and related to pathological features. The most predictive clinical/histopathological features were determined by Cox regression modelling. The 3-year survival probability was similar for patients with macroscopic and only microscopic extracapsular spread (33 and 36%, respectively, compared with 72% for patients with intranodal metastasis). The Cox model showed the most predictive factor was extracapsular spread followed by status of resection margins. Extracapsular spread should be incorporated into pathological staging systems. Even microscopic extracapsular spread is of critical importance and must be sought especially in small-volume metastatic disease.

Abstract
PURPOSE The "adequate" therapy of tongue cancer has not yet been determined. The authors report their experience with 58 N(0) patients to elucidate the role of elective neck dissection in surgical treatment of cancer of the tongue. MATERIALS AND METHODS The files of 58 N(0) patients with tongue cancer were evaluated retrospectively. In every patient, partial glossectomy continuous with neck dissection was the mainstay of the treatment. TNM staging, intraoperative N staging, pathologically confirmed cervical lymph node metastases and their levels, and clinical outcomes (local and regional recurrences) were recorded. The sensitivity and specificity of intraoperative staging was determined. RESULTS Fifty-four percent (31/58) of the patients presented as T(1), and 26% (15/58) as T(2). The overall occult metastasis rate was 29.3% (17/58). The occult metastasis rate for T(1) and T(2) lesions was 19.4% (6/31) and 26.7% (4/15), respectively. The sensitivity of intraoperative staging was 76.5%, and the specificity was 51.2%. CONCLUSIONS The rate of occult metastasis to the neck is too high in all tongue cancer cases to take the risk of regional recurrence, and the surgeon can not solely depend on neck palpation for determination of neck metastasis. Radiologic investigations and fine-needle aspiration decrease, but never reduce to zero the rate of false-negative examination. There is an obvious indication for neck dissection, even in early cases.

Abstract
Histologic evaluations of neck dissection specimens from carcinomas of the head and neck provide information required for disease staging, planning further treatment, and prognosis. Histologic evaluation performed adequately and accurately can and continues to provide a more accurate, meaningful, and promising means of formulating and predicting prognosis including risk of metastases. A multi-institutional study using comprehensive standardized histologic evaluation of histopathologic variables of primary tumor and cervical lymph nodes among homogenous patient groups receiving similar therapy is important. Histopathologic parameters remain an important adjunct parameter to clinical evaluation in guiding, planning treatment, and predicting prognosis for patients with head and neck cancers.

Abstract
The presence of cervical lymph node metastasis in patients with head and neck cancer is associated with an unfavorable prognosis. Reports vary as to whether various conventional radiographic studies, such as computed tomography (CT) and magnetic resonance imaging, confer an advantage over physical examination in the patient without clinical findings of cervical metastasis (N0). Positron emission tomography (PET) is a functional imaging modality that has recently been used for head and neck neoplasms. The use of PET in the evaluation of the N0-staged neck in 14 consecutive patients with squamous cell carcinoma (SCC) of the upper aerodigestive tract is reported. Seven patients (50%) undergoing 13 neck dissections had pathologic evidence of disease. PET scans were positive in five patients with pathologically confirmed cervical metastasis. PET scans were negative in seven patients (11 neck dissections) with no pathologic evidence of disease. PET scans were positive for unilateral cervical metastasis in two of three patients with involvement of a single lymph node. PET scans were positive in two of three patients with more than two lymph nodes involved. PET had an accuracy of 100% in the eight patients with SCC of the oral cavity. In patients with oropharyngeal or hypopharyngeal carcinoma PET localized cervical metastasis in two of four patients with neck metastasis. In the patient with an N0-staged neck on clinical examination, PET was found to have an overall sensitivity of 78%, specificity of 100%, positive predictive value of 100%, negative predictive value of 88%, and accuracy of 92%. CT demonstrated sensitivity of 57%, specificity of 90%, positive predictive value of 80%, negative predictive value of 75%, and accuracy of 76%. PET showed a trend in increased accuracy (P = 0.11) over CT. PET appears to be a promising diagnostic aid that may be applied when evaluating the N0-staged neck, especially for SCC of the oral cavity.

Abstract
PURPOSE To report the final results of a prospective randomized trial that aimed to evaluate efficacy and toxicity of concomitant postoperative radiotherapy and Cisplatin infusion in patients with Stage III or IV squamous cell carcinoma of the head and neck and histological evidence of extracapsular spread of tumor in lymph node metastase(s). METHODS AND MATERIALS Radiotherapy was delivered using a daily dose of 1.7 Gy for the first 54 Gy and 1.8 to 2 Gy until the completion of the treatment. Cisplatin 50 mg i.v. with forced hydratation was given or not every week (i.e., seven to nine cycles) concurrently with radiotherapy. A total of 44 patients were treated by irradiation only (RT group) and 39 by irradiation with chemotherapy (CM group). RESULTS The RT group displayed a higher rate of loco-regional failures as compared to CM group (41 vs. 23%; p = 0.08). The overall survival, the survival corrected for deaths by intercurrent disease, and the disease-free survival were better in CM group as compared to RT group with statistically significant differences. Survival without loco-regional treatment failure was better in the CM group, the difference being close to the level of significance (p = 0.05). Survival without distant metastases were comparable in the two therapeutic groups. Ten severe late complications were observed, four in the RT group (17%) and six in the CM group (22%). Cox univariate analysis confirmed the importance of the therapeutic modality in predicting the overall survival, the survival corrected for deaths by intercurrent disease, and the disease-free survival. CONCLUSIONS The present final report of this phase III study confirms preliminary results. The concomitant use of 50 mg weekly Cisplatin infusion and postoperative radiation improved loco-regional control and survival. No significant increase of late radiation complications was observed in the CM group.

Abstract
Cervical metastasis is the most important prognostic factor in head and neck cancer patients. The prognostic significance of extracapsular spread of tumor in metastatic lymph nodes has also been documented. The presence of extracapsular spread further reduces the survival by 50% in those patients with cervical metastatic disease. Most patients with clinically negative necks (stage N0) have a good prognosis. However, some of these patients will have neck disease and distant metastasis and will eventually die. Because the presence of extracapsular spread is a predictor of poor outcome, we hypothesized that extracapsular spread may be a factor in the subset of patients with clinically negative necks who have poor outcomes. One hundred nine patients with clinically negative necks who had undergone neck dissection were identified. Occult metastasis was observed in 34% of patients. In this group, extracapsular spread was present in 18 (49%) patients. Overall, 103 patients were evaluable, of whom 70 (68%) remain free of disease 2 or more years after treatment. A subgroup of 68 patients had histologically negative nodes, of whom 56 (82%) are free of disease. Of patients with extracapsular spread, only 5 (31%) of 16 are free of disease. This is in contrast to patients with metastasis confined to the lymph node, of whom 9 (47%) of 19 are free of disease. Statistical analysis of these data shows that for this sample size this difference is significant. The addition of radiation therapy did not improve outcome in these patients. Extracapsular spread predicts a worse outcome in patients with subclinical cervical metastasis. Alternative modes of adjuvant therapy are suggested because of the poor results of postoperative radiation therapy in patients with extracapsular spread.

Abstract
BACKGROUND A cell surface receptor (50 kd) has been recently identified in malignant cells that recognizes the tumor cell adhesive domain (ie, cysteine-serine-valine-threonine-cysteine-glycine [CSVTCG]) of thrombospondin (TSP). This CSVTCG-specific TSP receptor can be considered as a new tumor marker, and its concentration on the cell surface may correlate directly with the capacity of tumor cells to invade and metastasize. MATERIALS AND METHODS Six patients with primary, stages III and IV squamous cell carcinomas of the head and neck were studied. Tumor sections were specifically stained for this receptor with immunohistochemical techniques. The stained specimens were then subjected to computer-assisted image analysis. The area of positive staining and the heterogeneity of the pattern of staining were compared to peritumoral angiogenesis and clinical outcome of the patients. RESULTS The results indicate that those patients with a high and homogenous positive stain score (mean +/- standard error [SE] 78 +/- 5%) for the CSVTCG-specific TSP receptor had high microvessel density and died from metastatic disease within 12 months of initial treatment (correlation coefficients = 0.95 and 1, respectively). Patients with a low and heterogenous positive stain score for receptor (mean +/- SE 8 +/- 2%; P < 0.001) had low microvessel counts and remained disease-free for at least 2 years. There was no relationship between receptor density and histologic classification of the primary tumors. CONCLUSION The CSVTCG-specific TSP receptor, quantified through image analysis of immunohistochemical stained tissue sections, is highly predictive of clinical outcome in patients with squamous cell carcinomas of the head and neck.

Abstract
Many factors have been claimed to influence the clinical prognosis of cancer of the tongue, one of them being the inflammatory response at the advancing tumor border. In a retrospective study of 60 patients with squamous cell carcinoma of the oral tongue, lymphocytic peritumoral inflammation was not found to be an objective prognostic marker.

Abstract
PURPOSE The aim of the study was to determine preliminarily whether cell kinetic parameters evaluated using in vivo infusion of bromodeoxyuridine (BrdUrd) and flow cytometry, play a role as prognostic factors of loco-regional control in squamous cell head and neck carcinoma treated with radiotherapy. METHODS AND MATERIALS Between April 1989 and December 1991, 42 patients with unresectable Stage II-IV squamous cell carcinoma of the oral cavity, pharynx or larynx were given an infusion of BrdUrd solution prior to primary tumor biopsy sampling at 4-6 hr later. The simultaneous labeling S-phase fraction (LI) and duration (Ts) as well as the estimated potential doubling time (Tpot) were measured using flow cytometric analysis of BrdUrd and DNA content. Twenty-six patients received standard radiotherapy (70 Gy/35 fractions/7 weeks) whereas 15 patients were treated with the concomitant boost technique (75 Gy/40 fractions/6 weeks). RESULTS A complete set of flow cytometric data was available for 31 patients. The median value of LI, Ts, and Tpot were 9%, 9 hr and 5 days, respectively. Univariate analysis among the patients treated homogeneously by standard radiotherapy, indicated that local control was affected by Tpot value (p = 0.02). When the same analysis was performed for the patients treated with either standard radiotherapy or concomitant boost regimen, we found a p = 0.04. Thus, patients with a tumor Tpot value < or = 5 days had a significantly lower three-year local control than patients with Tpot > 5 days. Log-rank test univariate analysis showed, in addition, that nodal status was the strongest prognostic factor of local control (p = 0.005). Age, tumor stage, tumor site, performance status, grading, radiotherapy regimen, DNA ploidy and LI value were, instead, not significantly related to loco-regional control. Finally, when comparing the type of radiotherapy for tumors with Tpot < or = 5 days, we found a trend toward a better local control after concomitant boost regimen, with respect to standard regimen (p = 0.06). CONCLUSION The present preliminary results suggest that Tpot could play a role as additional prognostic factor influencing the disease outcome in head and neck carcinoma treated by radiotherapy.

Abstract
Of 1030 patients who underwent neck dissection (radical, modified or selective) in a 27-year period 103 had malignant neck nodes from a primary site in the head and neck with a histological diagnosis other than squamous carcinoma. There were 71 men and 32 women in this group with a mean age of 55 years. 28 patients had neck dissection as part of their initial treatment and 75 for later nodal recurrence. Five-year survival was 52% (40-63%). Survival was site dependent, best for thyroid tumours and worst for tumours of the major salivary glands (chi 1(2) = 6.52, P < 0.05). Histology significantly affected survival, best for papillary tumours and worst for melanoma and undifferentiated tumours (chi 1(2) = 3.85, P < 0.05). Survival was worse with advanced N stage but varied little with node level. The number of nodes invaded had a highly significant effect on survival (chi 4(2) = 23.94, P < 0.001), but extracapsular rupture had no effect. Advanced T stage at the time of surgery had a significant adverse effect on survival using univariate analysis, but this effect disappeared using multivariate analysis. In the 75 patients who had neck dissections for nodal recurrence the presence of a simultaneous recurrence at the primary site had no significant effect on survival. These patients had a better 5-year survival than patients having neck dissection for squamous disease, but the usual predictors of survival in squamous carcinoma do not always apply to non-squamous malignancy.

Abstract
In head and neck carcinoma, the finding of extracapsular lymph node extension and/or positive resection margins portends poor locoregional control and survival. The effectiveness of postoperative radiotherapy in these patients has been controversial due to insufficient studies comparing resected patients with those also receiving radiation. Between 1982 and 1988, 441 radical head and neck resections were performed at the Medical College of Virginia. Pathologic review of these cases identified 125 with extracapsular lymph node extension and/or positive resection margins. Of these, 43 had extracapsular lymph node extension only, 24 had both positive resection margins and extracapsular lymph node extension, and 58 demonstrated positive resection margins only. Surgery alone was performed in 71 of these patients while 54 cases received surgery and postoperative radiotherapy, (combined modality treatment) CMT. Radiotherapy doses ranged from 50 to 70 Gy. The surgery alone and combined modality treatment groups were comparable with respect to the distribution of positive resection margins and extracapsular lymph node extension. Slightly more CMT patients had clinical T4 disease compared with the surgery alone group (22% vs 14%). Slightly fewer combined modality treatment patients had clinical N0 necks than the surgery alone group (20% vs 29%). Multivariate analysis was performed with the variables T, N stages, radiotherapy, margin status, primary tumor sites, microscopic and macroscopic extracapsular lymph node extension, number of positive lymph nodes, number of nodes with extracapsular lymph node extension. Locoregional control was maintained at 5 years in 59% of the combined modality treatment group and 31% of the surgery alone group (p.0001). Subgroup analysis likewise reveals significant differences favoring the combined modality treatment group for positive resection margins only (49% vs 41%; p = .04), extracapsular lymph node extension only (66% vs 31%; p = .03) and extracapsular lymph node extension+positive resection margins (68% vs 0%; p = .001). Adjusted survival also shows a significant benefit of combined modality treatment vs surgery alone for the entire group (72% vs 41%; p = .001). Multivariate analysis revealed that the use of radiotherapy is a strongly favorable variable for local control and adjusted survival. Macroscopic extracapsular lymph node penetration and positive resection margins are unfavorable independent variables for local control. T-stage is the only variable predicting local control in the combined modality group. Extracapsular extension remains an important negative prognostic variable for survival in both treatment groups. In conclusion, this study demonstrates a locoregional control and survival benefit for postoperative radiotherapy in patients with the high risk pathologic findings of extracapsular lymph node extension and positive resection margins.

Abstract
Histopathologic malignancy score and DNA ploidy were investigated as prognostic factors for 72 cases of squamous cell carcinoma of the head and neck (HNSCC). The malignancy grading was based upon four different morphologic characteristics for the tumor cell population and four characteristics for the tumor-host relationship. DNA ploidy was determined through flow cytometry on fresh-frozen tumor samples. The median malignancy score was 20, with 71% of the tumors scoring less than 20 being diploid and 68% of the tumors scoring greater than or equal to 20 being nondiploid (p = 0.003). Univariate analysis revealed that tumors scoring less than 20 and diploid tumors had a significantly higher proportion of complete response and better survival as compared to tumors scoring greater than or equal to 20 and nondiploid tumors, respectively. There was a tendency toward better survival among patients without regional metastasis (N0) as compared with patients with regional spread (N+), whereas the other single factors, patient age, clinical stage, histologic grade, and tumor size did not correlate with prognosis. In N+ patients both malignancy score and DNA ploidy were predictive for survival, whereas in N0 patients only malignancy score was related to prognosis. A multivariate analysis showed that the combination of malignancy score and nodal status were the strongest predictors for survival. DNA ploidy did not contribute further information in this test, due to its close relation with the histopathologic malignancy score.

Abstract
High frequency (10-21 kHz) hearing thresholds were measured in 54 patients with Bell's palsy. In 25 (46%) of the patients the high frequency hearing was worse in the affected side, and in 16 (30%) better. The differences in the mean threshold between the two ears varied from 17.1 to 3.8 dB, being statistically significant at half of the frequencies measured. The findings support the idea that facial palsy is one manifestation of a lesion which extends beyond the VIIth cranial nerve.

Abstract
Two hundred fifty radical neck dissections, undertaken for mucosal squamous carcinomas of the head and neck, were reviewed with reference to pathological findings and their clinical implications. No major differences in descriptive surgical pathology were established between irradiated and non-irradiated resections. In general, irradiated dissections had lower total node counts and somewhat fewer nodal metastases involving a smaller number of different nodal groups. The topography of nodal deposits was similar in irradiated and non-irradiated resections. Palpable keratin granulomas (without intact tumor) were almost confined to irradiated patients. Transcapsular spread of tumor from involved lymph nodes was common: it was demonstrated in 160/188 'positive' dissections (85%) and was subclassified as 'macroscopic' in 90 and 'microscopic' in 70. The incidence and extent of transcapsular spread was similar in irradiated and nonirradiated resections. It was more frequently observed in association with large nodal masses but it was also regularly found with small nodal deposits less than 3 cm in diameter. Statistical analyses showed strong associations (p less than 0.0005) between the presence and/or extent of transcapsular spread and subsequent recurrence in the operated neck and overall survival. The predictive value of other clinical and pathological features vis-a-vis local neck recurrence such as numbers of involved nodal groups was weaker. Macroscopic transcapsulr spread emerges as the major prognostic factor for recurrent disease in the neck (p less than 0.0001). Attention is drawn to the advantages of accurate descriptive categories ('macroscopic', 'microscopic') for this critical prognostic feature.

Abstract
A series of 618 patients with neck dissections were performed in 455 consecutively admitted patients with head and neck carcinomas at the Istituto Nazionale Tumori, Milan, from 1976 to 1978. Clinical and pathologic node factors were considered in an effort to correlate lymph node involvement with prognosis. Actuarial survival decreased with the increase in the size of nodes, although no significant difference was found for all categories and the prognosis was poor when nodes were greater than 5 cm and/or hypomobile (33%, 5-year survival). The presence of histologically proven neck metastases significantly reduces the 5-year survival, and the presence of distant metastases correlates directly with the pathologic staging of neck nodes.

Abstract
The incidence, extent, and selected clinicopathologic correlations of transcapsular spread from metastatic tumor in the cervical lymph nodes have been investigated in 210 specimens obtained by radical neck dissection from 203 patients with squamous cell carcinomas of the head and neck. Transcapsular spread was detected in 137 of 159 (86 percent) positive specimens, and classified as macroscopic in 74 (54 percent) and microscopic in 63 (46 percent). Macroscopic transcapsular spread was seen most frequently in association with large nodal masses more than 3 cm in diameter (48 of 70 specimens, 69 percent), but also occurred in some specimens with smaller lymph nodes less than 3 cm in diameter (26 of 67 specimens, 39 percent). Anatomic structures most commonly invaded in areas of neck dissection with macroscopic spread from nodal metastases were skeletal muscle (39 dissections) and the adventitial coat of the internal jugular vein (27 dissections). Macroscopic transcapsular infiltration was associated with a high incidence (44 percent) of recurrent tumor in the ipsilateral neck, particularly within 12 months of surgery. Microscopic transcapsular growth was associated with a lower incidence (25 percent) of recurrent tumor in the ipsilateral neck but the difference did not reach statistical significance. Similar recurrence figures (32 percent) were found in the minority of patients whose nodal disease was intracapsular at the time of neck dissection. More precise definition of the morphologic extent of transcapsular spread could be important in clarifying its clinicopathologic correlations.

Abstract
A retrospective clinico-pathological study has been carried out in a series of 405 patients with squamous cell carcinoma of the head and neck who underwent a total of 484 radical neck dissections. The recurrence rate in the neck in 327 patients who had histological positive nodes was 21.1%. Recurrence in the neck after a standard radical neck dissection almost invariably proved fatal. A statistical analysis has been carried out to evaluate the clinical and pathological factors which are of importance in regards to recurrence in the neck. Histological factors such as extra-nodal spread and the number of histological positive nodes have been shown to be of much more prognostic importance than clinical parameters. When corrections are made for interdependencies between variables, histological extra-nodal spread proved to be the most important single prognostic factor (P less than 10(-7)).

Abstract
A complete response to induction cis-platinum bleomycin chemotherapy significantly increases the probability of local tumor control and overall disease-free survival. Factors that favor a good response to chemotherapy are tumor histology (well differentiated), location of the primary site (oral cavity and oropharynx), nodal status (N0) and size of the primary lesion (t3 better than T4). Increased cellular maturation after chemotherapy correlates with an improved clinical response. The importance of induction and maintenance chemotherapy in the treatment of advanced head and neck cancer still needs to be determined with larger randomized series. Reliable predictors of therapy outcome are needed for realistic treatment planning, especially when the potential morbidity is considered.

Abstract
A preliminary clinico-pathological survey is presented of radical neck dissections from 50 patients with advanced (T3, T4) squamous carcinomas of the head and neck, previously treated by irradiation and combination chemotherapy. The total yield of lymph nodes (1411) from these dissections was high--mean of 28 nodes/dissection, range 8-60; the proportion of nodes containing metastatic carcinoma was low--100 (7%)--with only 1 or 2 nodal masses/dissection in most instances. The involved nodes tended to be concentrated in 1 or 2 anatomical groups, principally in the upper anterior neck, with apparent sparing of nodes in the posterior triangle. There was a high incidence (88%) of transcapsular spread. Keratin granulomas, with or without intact metastatic carcinoma, were commonly found; on occasions they formed large masses simulating nodal metastases. The morphological patterns in uninvolved lymph nodes were shown to be of no prognostic significance. Initial data on postoperative follow-up indicated a crude survival of 52% (24 patients) at 30 months. Most deaths (80%) occurred within 12 months of major surgery; the majority (72%) died with residual malignant disease; and uncontrolled primary tumour, particularly in the oral cavity and oropharynx, was found more frequently than metastatic disease in the neck or elsewhere. Clinical implications are discussed with reference to the use of modified radical neck dissection in the surgical salvage of this poor-risk group of previously irradiated patients.

Abstract
In recent years, there has been increased interest in defining what constitutes good quality of care for the terminal cancer patient. Progress in this area depends upon adequate knowledge of the problems in the terminal period for patients with cancer in specific sites. The present study is a survey of the final period of life in 60 head and neck cancer patients. The average survival time from diagnosis to death was 17.2 months. The mean time of hospitalization was 4 months. Pain was a problem in 85% of the patients, with feeding problems in 62% and respiratory difficulties in 43%. Eighty-six percent of the patients died in a hospital setting, with the average duration of the final hospitalization being 68 days. Our analysis documents the complex problems in the terminal phase of a head and neck cancer patient's life. These problems challenge medical facilities caring for such patients to develop programs that will provide the best possible levels of care for head and neck cancer patients and to develop approaches that will reduce the suffering experienced by the patient's family.
