Cancer

A malignant growth or tumor caused by abnormal and uncontrolled cell division. The hallmark of cancer is its potential ability to invade neighboring tissue or to spread (metastasize) to other parts of the body through the lymphatic system or the bloodstream. Early cancers may have done neither, remaining localized to the tissue of origin. The majority of cancers in the head and neck are classified as carcinomas.

Laser Removal of Vocal Cord Cancer with Bilateral Disease

For treatment of early vocal cord cancer, both laser excision and radiotherapy are in competition as good treatment modalities. See also Early Vocal Cord Cancer: Remove with a Laser, or Radiate? Often, radiation is used when disease is bilateral, in the interest of preserving voice. This is an example of the ability to do fairly extensive laser surgery bilaterally, yet preserving good voice. This man had a friend who had severe difficulty with radiation, and he was therefore opposed to that option.

Vocal cord cancer (1 of 10)

This 70-something man is a longterm smoker. Here you see an obvious cancer of his left vocal cord (biopsy-proven), but disease on the right side as well that is more superficial.

Stippling (2 of 10)

At higher magnification and using narrow band light, some of the vascular abnormality (stippling) is better seen (arrows).

Granulation (3 of 10)

A week after definitive excision of his cancer. Typical early wound appearance, with a suggestion of granulation on the left side (right of photo).

Reparative Granuloma emerges (4 of 10)

Six weeks later, healing is nearly complete other than a typical reparative granuloma on the left (right of photo).

Granuloma interferes with voicing (5 of 10)

During voicing, the granuloma interferes with closure, explaining in part his ongoing severe hoarseness. Note also the typical medial-to-lateral capillary reorientation.

Granuloma fades away (6 of 10)

Now 3 months postop, the granuloma is smaller. Classic capillary reorientation is again seen.

Closer view (7 of 10)

Under strobe light, closed phase of vibration. Voice is highly functional, since the granuloma no longer interferes with closure.

Granuloma cleft (8 of 10)

Open phase of vibration under strobe light shows the bilobed, clefted nature of the granuloma, where the right vocal fold “fits into” the granuloma (arrows at cleft).

Blood tattoo (9 of 10)

At nearly 5 months postop, the granulation tissue has auto-detached, leaving only a small “blood tattoo.” Here, under strobe light and closed phase of vibration.

Open phase of vibration (10 of 10)

Voice is somewhat hoarse but highly serviceable, and “better than it has been in years,” according to the patient.

Squamous cell carcinoma (1 of 6)

This man developed hoarseness across a few months. Biopsy elsewhere revealed squamous cell carcinoma, seen here on both vocal cords. Based upon a friend’s experience, he rejected radiotherapy, opting for laser resection, knowing it could be very hard on voice.

Tumor on the vocal cords (2 of 6)

At closer range and under narrow band (blue-green) light to accentuate the vascular abnormalities associated with this tumor.

Granuloma delays voice recovery (3 of 6)

Six weeks after superficial laser cordectomy, the larynx is almost healed with the exception of a small granuloma, left vocal cord (right of photo). When healing includes granulation, voice recovery is delayed as the granuloma resolves.

Closer view of granuloma (4 of 6)

He has hoarse but functional voice, but under strobe light, the granuloma prevents vibratory closure. Note the medial-to-lateral capillary reorientation so typical after laser cordectomy.

Granuloma is smaller (5 of 6)

Now 3 ½ months from surgery, voice has improved further and he considers it “75%” of original...One can see that the granuloma is smaller.

Granuloma doesn't impede voice (6 of 6)

Note that the granuloma no longer prevents vibratory closure and this explains further improvement of voice. Compare with photo 4.

Breaking cancer "rules" intelligently with use of laser
Visual Portfolio, Posts & Image Gallery for WordPress

Post radiotherapy stage (1 of 8)

This woman had completed radiotherapy elsewhere many months ago for early vocal cord cancer. Recent biopsy of these lesions shows persistent cancer. At the same time, she is under treatment for unrelated stage IV lung cancer. Standard treatment here would be total laryngectomy.

Laser surgery typically not acceptable (2 of 8)

Under narrow band light and at closer range. Not only due to failure of radiation to cure, but also because this tumor crosses the anterior commissure (where the two vocal cords meet at the bottom of the photo), the widely accepted "rule" is that she should undergo total laryngectomy. The blue lines are located in the same place in the following photo.

Laser removal of tumor with careful followup (3 of 8)

In light of the patient’s uncertain future due to advanced lung cancer, her near-refusal of total laryngectomy, and with detailed inclusion of patient in “breaking the rules” thinking, the tumor was removed with the laser. Tissue margins were negative. Still, tumor behavior is not as predictable as it would be in a previously-untreated patient. Careful followup is therefore critical. Hashmarks show area of removal, to include everything even faintly abnormal-looking and the blue lines are located in the same place in the previous photo.

Second view post laser surgery (4 of 8)

Better view of the anterior commissure, where soft tissue was removed all the way to the inner perichondrium of the thyroid cartilage at the arrow.

Six months post laser surgery (5 of 8)

Nearly 6 months after laser surgery. Healing is complete. No obvious tumor is seen. The patient has developed very serviceable false cord voice (see photos 7 and 8).

Blood vessels stable two months post surgery (6 of 8)

Narrow band light allows more intense monitoring for aberrant blood vessels that might indicate tumor regrowth before there is any visible bulk. Vessels in the area of arrows have been stable for 2 months but require careful comparison with future examination photos.

Open phase of false vocal cord phonation (7 of 8)

Supraglottic cancer (1 of 4)

Middle-aged woman with sore throat, discovered to have a circumscribed exophytic squamous cell carcinoma at the petiole and anterior false cords.

Supraglottic cancer (2 of 4)

Closer view, showing the aberrant tumor vessels especially in the inferior half of the tumor, with less “white-out” from light overexposure.

Supraglottic cancer (3 of 4)

As is often the case, this tumor “respects” the ventricle, meaning it does not cross the plane of the ventricle (entrance at dotted line) to invade the true cords. An instrument could lift the inferior border of the tumor to show that the true cords aren’t invaded; the tumor is simply overlapping them.

Supraglottic cancer (4 of 4)

Under narrow-band lighting, the tumor’s aberrant vessels and its relationship to both the true and false cords are clearer. This is a supraglottic (not transglottic) tumor, likely amenable to outpatient endoscopic laser resection, and management of lymphatic compartments of the neck, depending on individual circumstances, via observation, radiotherapy, or selective neck dissection.
Hypopharyngeal Cancer, before and after Surgery

Hypopharyngeal cancer (1 of 10)

Years after successful radiotherapy for glottic cancer, during a routine, yearly follow-up examination, a new hypopharyngeal cancer (invasive squamous cell carcinoma) is barely seen, at arrow. (For reference, X marks the same location in the larynx throughout this series.)

Hypopharyngeal cancer (2 of 10)

Trumpet maneuver begins, to splay open the post-arytenoid part of the posterior pharyngeal wall (arrows and dotted lines), as well as the pyriform sinuses on each side. The tumor is now seen clearly. (Note the change of perspective from photo 1, using X as a reference point.)

Hypopharyngeal cancer (3 of 10)

Similar view to photo 2 (still with the trumpet maneuver), but now with the tumor outlined.

Hypopharyngeal cancer (4 of 10)

Closer view than photos 2 and 3 (again, still with the trumpet maneuver), with the tumor still outlined. Radiation is not an option for this tumor because of prior larynx irradiation; an attempt at laser surgery was selected.

Hypopharyngeal cancer: 1 week after surgery (5 of 10)

Months after laser resection, panoramic view, showing the swallowing “crescent” (within dotted lines), at the upper limit of where the laser resection occurred. There is surgical stenosis at the entrance to the esophagus (shown in the next photo). This stenosis affects swallowing of solid food, but the patient says this is no problem for him, if he eats a little more slowly and chews well.

Cancer: HPV Subtype 16 (1 of 5)

Cancer, in a patient with HPV subtype 16. The divot and blood seen on the left vocal cord (right of image) are the result of a biopsy performed elsewhere (not by BVI physician) earlier the same day as this examination.

Cancer: HPV Subtype 16, after radiation therapy (3 of 5)

Six weeks after the end of radiation therapy, the tumor is no longer seen. However, part of the left cord (right of image) is missing, due to sloughing of the tumor that had eaten away part of the cord’s normal tissue.

Cancer: HPV Subtype 16, after radiation therapy (4 of 5)

Phonation. Strobe light, open phase of vibration, shows that the margin of the left cord (right of image) is at a lower level than the right’s, due to loss of some of the bulk of the cord where the tumor died and sloughed away.

Cancer: HPV Subtype 16, after radiation therapy (5 of 5)

Vocal cord cancer (1 of 8)

Superficial cancer involving both vocal cords. This is stage 1 disease (T1B). The greatest bulk is on the right posterior cord (left of image), but the majority of both cords is involved with at least superficial disease. A faint dotted rectangle indicates the zoomed-in area seen in photo 2.

Vocal cord cancer, during radiation (4 of 8)

Postcricoid / hypopharyngeal mucositis. In this view, the patient is performing a so-called trumpet maneuver to splay open the lower throat. The radiation delivered to the vocal cords (which inhabit the airway but are hidden here due to the momentary constriction of the laryngeal vestibule, at arrows) also causes superficial ulceration of the swallowing passage (upper half of the photo), directly behind the vocal cords. On occasion, if tissue reaction and mucositis are much more severe than seen here, a stricture can form, requiring dilation.

Vocal cord cancer, 2 months after radiation (5 of 8)

Two months after radiation is complete, showing that the tumor is gone, and the mucositis has resolved. There is a small anterior commissure web (at arrow) just below the free margin of the cords. The patient’s voice can nevertheless pass for normal.

Vocal cord cancer, 4 months after radiation (6 of 8)

Now four months after the end of radiation. Close-up view of the postcricoid / hypopharynx regions (compare with photo 4 in this series). Mucositis here is resolved as well, and there is no stricture.

Recurrent cancer (1 of 8)

Cancer, recurrent after radiotherapy. Cancer treatment 'rules' dictate a radical anterior commissure resection or more likely, total laryngectomy.

Closer view (2 of 8)

Closer view. The rules just invoked came about because cancer that crosses the anterior commissure is not to be trusted and especially after radiotherapy; cartilage involvement is far more likely; furthermore, laser resection might trigger radionecrosis. With careful patient involvement, an exception to these 'rules' was made here due to concomitant Stage 4 lung cancer of highly uncertain prognosis.

Vocal cord lesion (1 of 4)

Middle aged man with hoarseness and a left vocal cord lesion (right of photo) suspicious for cancer. After extensively educating the patient about options he would have if this were proven to be cancer, a single trip to the O.R. was planned for both frozen section, and possible definitive laser excision.

Closer view (2 of 4)

Though this looks bulky, some "large" tumors can be removed definitively with the laser, if they are mostly exophytic (growing outwards) rather than endophytic (deeply infiltrating).

Removal of tumor (3 of 4)

Frozen section was positive for squamous cell cancer, and much of the tumor was removed, but an endophytic (infiltrative) growth pattern diverted the plan to radiation therapy.

If significantly more vocal cord were removed, voice might also have been excessively compromised.
Progressive Cricoarytenoid Joint Fibrosis/ Fixation as a Late Complication of Radiation
Visual Portfolio, Posts & Image Gallery for WordPress

25 years post radiotherapy (1 of 4)

During 25 years since radiotherapy for vocal cord cancer, voice had been “80%” and breathing normal. In recent years, voice is deteriorating; breathing also seems restricted during exertion. During “quiet breathing,” the vocal cords are in only partial abduction, due to fixation/ partial fixation of the crico-arytenoid joints. This glottic chink for breathing is likely less at night during sleep, explaining noisy breathing and the need for CPAP.

Fibrosis (2 of 4)

Here, the patient is sniffing, in order to reveal maximum possible abduction. Note that the right vocal cord (left of photo) seems “frozen” but not paralyzed (no atrophy) due to fibrosis of the right cricoarytenoid joint. The left vocal cord (right of photo) lateralizes incompletely. Note as well, post-radiation capillary ectasia.

Closed phase (3 of 4)

Under strobe light, closed phase of vibration. The left cord can move to the midline, and there is no sense of atrophy of either cord.

Open phase (4 of 4)

Open phase of vibration shows that only the left vocal cord mucosa (right of photo) is flexible, and is the source of all of the patient’s voice. The right cord mucosa (left of photo) is stiff and non-vibrating at all pitches. Without an examination from 25 years earlier, it is unknown where this represents early post-treatment stiffness (scarring from biopsy, etc.) or whether it is also the result of progressive fibrosis.

Forty years post-radiation (1 of 8)

This photo is taken forty years after curative radiation for a vocal cord cancer. Four decades of progressive radiation fibrosis (“leatherization”) has taken away arytenoid movement so that this is the maximum opening. The patient is exercise-intolerant and makes loud inspiratory breathing noises while sleeping. Her voice is also very poor.

Involuntary inspiratory voice (2 of 8)

With sudden inspiration, the darker mucosa (at the arrows) indraws and vibrates, making an involuntary inspiratory voice.

Only capable of high pitch (3 of 8)

Other than a stage whisper, she can only make a very high pitch, because the only mucosa capable of vibration is the small segment indicated by the arrows.

Open phase vibration (4 of 8)

Again under strobe light, this is the open phase of vibration, with arrows again indicating the short segment of mucosa that can oscillate.

One week post-commissuroplasty (5 of 8)

A week after posterior commissuroplasty, the patient’s breathing is much improved. Despite the distant view, the “cookie bites” taken from the posterior cords are visible.

Rapid inhalation, closer view (6 of 8)

In a much closer view, the posterior vocal cord divots are seen well. The segment of flexible mucosa is indrawing here as the patient inhales rapidly (at arrows).

Three months post-surgery (7 of 8)

Three months after the laser surgery, the patient continues to say the improvement of breathing is “large.” In this distant view the full reason why is not seen.

Closer view, post-surgery (8 of 8)

In a closer view, as is always the case after complete healing, the divots are smaller than just after surgery.

Vocal cord cancer (1 of 8)

Bulky but superficial right vocal cord cancer (arrow, left of photo).

Voice-making with tumor (2 of 8)

Voice-making position. Notice the more lateral turning of the right vocal process (left of photo) as compared with the left (right of photo). As the remaining series shows, it is impossible to know if this is compensation for the bulk of tumor, or weakness of the LCA muscle.

One week post-removal (3 of 8)

A week after definitive removal, swelling, early granulation, and a division of the wound into upper and lower “lips” that must bind together with healing.

Voice-making, post-removal (4 of 8)

Note again the lateral turning of right vocal process (arrow, left of photo).

Six weeks post-op (5 of 8)

Six weeks after surgery, the wound is “bound together,” and there is a residual granuloma on the upper surface anteriorly (arrow).

Voice-making, post-op (6 of 8)

Making voice, there is still that peculiar lateral turning of the vocal process on the right (left of photo).

Four months post-op (7 of 8)

Now a full 4 months since laser excision, the cord is fully healed though still pink as expected. The anterior upper surface is coated with mucus.

Voice-making, four months post-op (8 of 8)

Making voice, again that lateral deviation of the right vocal process (arrow, left of photo). Voice is very functional but a little weak. Vibratory blur is greater for left than right cord.

Healing post-laser excision(4 of 4)

Now at 18 weeks after laser excision, healing is truly complete. Even under narrow band light and at close range, no vascular abnormality or leukoplakia is seen. Voice is remarkably good, without audible " effort," or syllable dropouts. Obviously, close follow up is required.

Post-laser excision (3 of 4)

10 weeks after laser excision, healing is nearly complete. Stippled vascularity is no longer seen; the medial-to-lateral reorientation of capillaries often seen after laser excision is seen especially on the right vocal cord (left of photo).

Leukoplakia and Stippled Vascularity(2 of 4)

At closer range under narrow band light, areas of leukoplakia and stippled vascularity are seen more clearly; all of this must be removed. The options are laser excision, partial laryngectomy, and total laryngectomy. Laser excision was selected as the "next step."

Return of cancer (1 of 4)

Eight years after radiotherapy for early vocal cord cancer, cancer has returned in a man who never stopped smoking. Radiotherapy is no longer an option. Here, we have bilateral disease.

squamous cell carcinoma (1 of 6)

After biopsy performed elsewhere revealed squamous cell carcinoma, this right vocal cord cancer (left of photo) is scheduled to be treated for cure via laser excision.

1 week after laser excision (2 of 6)

A week after laser excision, the typical upper and lower "lips" swell at the margins of resection will need to heal back together to re-establish a normal vocal cord contour.

Difficulty speaking (3 of 6)

As the vocal cords approach each other in preparation for producing voice, the upper and lower lips with central depression are seen more clearly.

Natural granulation after laser excision (4 of 6)

At approximately 2 months after laser excision, healing is nearly complete and voice very functional. There is a round granuloma (exuberant healing response) that will soon fall off spontaneously. Every patient is told about possible granulation of this sort, so that they do not worry that this is a tumor recurrence.

Abnormal capillary pattern (5 of 6)

A year after surgery, the patient's voice can pass for normal. Under strobe light, this closed phase of vibration shows the good match of the vocal cord margins. The regenerated mucosa of the right (upper part of photo) vocal cord has a typically abnormal (but healthy) post-laser capillary pattern.

Stiff right vocal cord (6 of 6)

Here during the open phase of vibration, one can see that the right vocal cord is stiff (as expected after laser surgery of any depth) and does not vibrate well. Voice sounds virtually normal, however, due to the precise match of the margins and normal left vocal cord vibration (see again, photo 5). At the time of this posting, this person has remained free of disease for 8 years, and has no sense of vocal limitation.
