80s Punk Rock Singer Lou Koller, 58, From the Group ‘Sick of It All’ Receives Added Support From Fellow Bandmates Who Say He’s ‘Still Fighting’ Esophageal Cancer More Than a Year After Diagnosis

In the Spring of 2025, Koller announced that he had reached remission after undergoing initial treatment. However, by the Fall of 2025, he revealed his cancer had returned.

“It’s back to square one and start the treatments again,” he said in the September 2025 update.

“The treatments are going okay. They’re not really doing much,” Koller shared in a recent Instagram update.

“I’m kind of at a stalemate, where the tumors aren’t growing, and they’re not spreading, but they’re not shrinking either.”

“It’s rare these days that I just do surgery for a patient with esophageal cancer. They’ve often gotten other treatments,” Dr. Brendon Stiles, a thoracic surgeon at Montefiore Medical Center, tells SurvivorNet.

“Remarkably, with very early stage disease, stage one, a patient can often have their tumor resected endoscopically, through a scope down their esophagus, without the need for invasive surgery. That’s a very selected group of very early, invasive cancer, but increasingly, as we do more endoscopies, we’re able to find those patients,” Dr. Stiles added.

WATCH: Explaining an Endoscopy Procedure

“The normal esophagus on endoscopy looks similar to the inside of your lips or cheeks,” Dr. Whit Burrows, a thoracic surgeon with the University of Maryland Medical System, tells SurvivorNet. When doctors perform an endoscopy to check for esophageal cancer, they’re looking for changes in that smooth, uniform lining.

Signs that may raise concern include:

• A loss of the esophagus’s usual uniform appearance
• Lesions
• Irregular or uneven areas
• Disrupted symmetry

In stage 1 esophageal cancer, symptoms are often absent, and the disease is typically found during an endoscopy, Dr. Burrows explains. At this early stage, the cancer hasn’t penetrated the esophageal wall.

“It’s a very local problem,” Dr. Burrows says. “If it’s very, very superficial, you don’t even need surgery. You can actually treat it through the endoscopy.”

Chemotherapy plays a vital role in treating esophageal cancer, whether it’s adenocarcinoma (a type of esophageal cancer) or squamous cell carcinoma (a type of esophageal cancer). The specific drugs used depend on the cancer type and individual patient factors.

“Chemotherapy is typically a drug that swims through your body, killing off cancer cells wherever they are—whether they are in your esophagus, in your great toe, in your hip, or in your liver,” Dr. Burrows said.

“So, [it’s] very different from surgery, where we locally remove the cancer, or radiation therapy, when we don’t remove it, but we locally treat it.”

The goals of chemotherapy include:

• Shrinking tumor size
• Reducing the number of cancer cells in the body
• Lowering the risk of cancer spreading
• Easing current symptoms

Treatment is typically given in cycles, allowing the body time to recover between sessions. Duration and dosage vary based on the patient’s condition and response.

Formed in 1986, “Sick of It All” has released 11 full-length albums, according to the band’s official website. They delivered hardcore staples like “Step Down,” “Built to Last,” and “The Blood and the Sweat.” Their legacy looms large — and so does the community rallying behind Koller.

Esophageal Cancer: Why Early Detection Is Critical for This Often-Silent Disease

“Esophageal cancer, we know, is a tough one,” Dr. Stiles said.

“It’s one of the cancers with some of the lowest cure rates out there. But like many cancers, if we find it early, we can often treat it effectively—either with surgery, with surgery and chemotherapy, or with chemotherapy and radiation,” Dr. Stiles continued.

Esophageal cancer is notoriously difficult to detect in its early stages. Its symptoms are often subtle, easily mistaken for common digestive issues, which can delay diagnosis and treatment.

Common Symptoms to Watch For

Because early signs can mimic everyday discomforts, it’s important to take persistent symptoms seriously. Known indicators include:

• Pain or difficulty swallowing
• Unexplained weight loss
• Pain behind the breastbone
• Persistent hoarseness or cough
• Indigestion or heartburn
• A lump under the skin (often near lymph nodes)

“Symptoms include things like … they’re losing weight, they’re having some burning in their esophagus or their chest, they’re having trouble or pain with swallowing,” explained Dr. Sofya Pintova, a hematologist and oncologist at Mount Sinai Cancer Center.

“That will often lead to a medical evaluation.”

How Esophageal Cancer Is Diagnosed

Diagnosis typically begins with an endoscopy—a procedure where a gastroenterologist inserts a camera down the esophagus to examine the tissue and look for abnormalities.

“If they see an area that is suspicious for a mass, or if they see a mass, they may biopsy it,” Dr. Pintova said.

“And if the biopsy confirms cancer, the next stage is usually staging.”

Types of Esophageal Cancer

There are two primary types, each originating in different cells of the esophagus:

• Squamous Cell Carcinoma: Forms in the thin, flat cells lining the inside of the esophagus
• Adenocarcinoma: Begins in glandular cells that produce mucus and other fluids

Staging the Disease

Once diagnosed, doctors determine the cancer’s stage—ranging from 0 to 4—which helps guide treatment decisions and predict outcomes. Earlier stages are more treatable, while later stages often require more aggressive, multi-modal therapies.

How Doctors Decide the Best Treatment Path for Esophageal Cancer

Esophageal cancer treatment isn’t one-size-fits-all. It depends on the tumor’s stage, location, and its impact on the patient’s ability to eat and function. Dr. Raja Flores, a thoracic surgeon with Mount Sinai Health System, explains how physicians determine the right approach.

“As a surgeon, you’re trying to figure out what kind of patient requires surgery, chemo-radiation plus surgery, or just chemotherapy, or just chemotherapy and radiation,” Dr. Flores told SurvivorNet.

The tumor’s depth within the esophageal wall plays a major role in treatment planning. Early-stage tumors—known as T1 lesions—are confined to the surface of the esophageal mucosa.

“Basically, if you have a tumor that is considered a T1 lesion … sometimes they can remove that with an endoscope,” Dr. Flores said.

“There are some situations where T1 tumors, which are very early-stage, can be removed with surgery alone.”

As the cancer progresses to T2 or T3 stages, it penetrates deeper into the esophageal wall. These cases typically require a more aggressive approach.

“When it gets a little more advanced, T2, T3, where it goes through the thickness of the wall of the esophagus, that frequently requires chemotherapy and radiation, followed by surgery,” Dr. Flores added.

In cases where the tumor causes a significant blockage—making it difficult or impossible to swallow—radiation may be the first step.

“When a patient comes in with a large obstruction, which cannot be removed with just surgery, the first move may be to send this patient to the radiation oncologist to get treatment started,” Dr. Flores explained.

“The majority of the time, you’ll get a response, things will open up, and you will be able to eat.”

Ultimately, symptoms and the presence of metastasis guide whether a patient receives chemotherapy alone or in combination with radiation.

“What determines whether you can get that combination of chemotherapy and radiation depends on your symptoms,” Dr. Flores said.

“Symptoms really dictate whether or not you’re going to get radiation there, but also, do you have distant disease? If you have a tumor in the middle of the chest but a metastasis somewhere else … if you don’t need radiation to open things up so you can swallow, usually in those cases they will just give you chemotherapy.”

Chemotherapy for Esophageal Cancer: Common Drug Combinations and Side Effects

Chemotherapy plays a central role in treating esophageal cancer, often used alongside surgery or radiation, depending on the stage and type of the disease. Most patients receive a combination of two or three drugs to maximize effectiveness.

Frequently Used Chemotherapy Drugs

The most common agents include:

• Fluorouracil (5FU) or its oral form Capecitabine (Xeloda)
• Platinum-based drugs: Cisplatin, Oxaliplatin, or Carboplatin
• Taxanes: Paclitaxel or Docetaxel

Common Drug Combinations

Doctors tailor regimens based on tumor type, location, and patient health. Some widely used combinations include:

• Cisplatin and capecitabine (CX)
• Cisplatin and fluorouracil (CF)
• Epirubicin, cisplatin, and capecitabine (ECX)
• Epirubicin, cisplatin, and fluorouracil (ECF)
• Carboplatin and paclitaxel
• Fluorouracil, oxalipatin, and docetaxel (FLOT)

These combinations are selected to attack cancer cells from multiple angles, improving the chances of shrinking tumors and preventing spread.

While chemotherapy can be life-saving, it often comes with side effects that vary in intensity. Common reactions include:

• Nausea and vomiting
• Hair loss or thinning
• Fatigue and weakness
• Peripheral neuropathy (nerve damage)
• Cardiotoxicity – irregularities causing damage to the heart rhythm or vascular function

Doctors monitor patients closely and may adjust dosages or provide supportive medications to manage these effects.

Questions to Ask Your Doctor

If you are diagnosed with esophageal cancer or are experiencing concerning symptoms compelling you to seek further examination, here are a few questions you can ask your care team.

• What type of esophageal cancer do I have?
• How will I receive chemotherapy treatments? Will I need a port?
• How often will I have chemotherapy? For how long?
• What are the risks and benefits of treatment with these drugs?
• Will my health insurance cover my treatment with this drug?
• What are the common side effects of the chemotherapy I will receive?
